Introduction: Vertical Mosaic LEGO Portraits - Everything You Needed to Know!

Making a mosaic image from LEGO pieces is nothing new -- in fact, a lot of well-known master LEGO builders have done all sorts of mosaic images, both flat/horizontal as well as vertical. Horizontal mosaics -- or tiled pictures -- maintain more accurate cell size, as 1x1 LEGO pieces are perfectly square from the top, as opposed to viewing from the front, in which bricks are slightly elongated by a few millimeters. That being said, vertical mosaic portraits can tend to appear more stretched-out when completed, but the advantage is, however, that vertical mosaics can have greater detail for blending colors. For instance, in a horizontal tile piece, you're limited to square tiles and plates, whereas with vertical pictures, you can mix and match thickness and various colors to create cool effects and illusions. Vertical LEGO mosaics can also be incorporated into other creations, such as making portraits for walls inside structures and whatnot: let's say you're making a castle, and you want the walls to have mosaic images as decorations. Also unlike a flat LEGO mosaic, a vertical image can have any thickness; my portraits have almost all been made with a collage of 1 x 2 bricks that face sideways -- thus making the portrait two bricks thick.

In this tutorial, I'll show you the proper steps, from choosing an image, preparing it for reference, mapping out colors, obtaining LEGO pieces, assembling a sturdy base, and even a few tricks and tips for easing production.

Step 1: Determining Your Image

For making a mosaic portrait, you're only limited to your ability to snap plastic bricks together -- as well as being limited to your wallet, and being limited to space in your domicile. That being said, the bigger the picture, the bigger the final product -- thus, the more expensive the project, and the greater space taken up in your house and/or on your table. Every amateur wants to immediately jump into an ambitious project and try to make a LEGO portrait that rivals a Byzantine icon like St. Demetrios at an Orthodox Church -- but the problem is, one tiny pixel on your screen equates to an entire LEGO brick, which is roughly 1 centimeter. In Super Mario Bros. 3, the standard size for the game's item sprites is 16 x 16 -- now translate that to LEGO sizes, and one little fire flower as a LEGO portrait is almost as big as an iPad screen.

Here's a little more reference to give you an indication of pixel size versus LEGO size: in the winter of 2013, I was commissioned by Nintendo of America to build a store display for the release of LEGO City Undercover at Rockefeller Center, and a few of my displays involved mosaic portraits. Please note: I'm also a really tall person -- yet, as you can see, a tiny pixel image on the screen will balloon up into a large portrait-sized image when built from LEGO bricks. When deciding what sort of image you'd like to create, always be sure to determine if in fact the final creation won't be too big and bulky to make.

You also don't have to limit yourself to video game sprites. I simply chose them for most of my recent mosaics, since retro games themselves were heavily pixelated and much akin to a LEGO creation -- and of course, because I was at the time being paid by Nintendo of America, hence relevancy was key. I also made a portrait of LEGO City Undercover's protagonist Chase McCain, which didn't in fact contain any sprites per-se -- rather it was a modified image of his model from the game (which is 3D). That being said, you can make a mosaic portrait out of any reference image -- video game or person, or even an original arbitrary piece that doesn't require reference photos.

Step 2: Choosing Colors

Picking colors can be a challenge for the novice builder. When a lot of folks think of LEGO, typically they imagine a bunch of bulky blocks only available in primary colors. The fact of the matter is, LEGO Group has come quite a long way in the past years, and as of now, thousands of types of pieces exist, and well over a hundred different colors are available. To see a complete unofficial guide to LEGO colors, refer to this link. However, not all LEGO colors are easily available in large quantities nor affordable, thus it's best to keep your mosaic creations within the confines of standard colors, with a minimal usage of rare colors. In this step, I'll give you the honest, personal facts about LEGO color rarity, rather than having you give up your dreams of building a mosaic portrait containing colors that are unavailable for cheap.

For starters, there are over 150 different colors -- including transparent, metallic, pearl, glitter, and others -- but for the sake of simplicity, I'll explain the basics of using colors efficiently, which you'll see in the color chart. Standard colors are abundant and relatively cheap in bulk. The basic colors of LEGO pieces encompass the majority of the library of parts -- in other words, virtually any LEGO piece created can usually be found in one of the standard colors. These include black, blue, green, red, yellow, reddish brown, light bluish grey, dark bluish grey, and white. If you decide to build your mosaic of these colors, you should have no problem finding pieces and getting them for a reasonable price.

Next we have uncommon colors; these particular colors may be a bit harder to find and would thus be slightly more expensive to purchase in large quantities. Occasionally the LEGO Stores might have entire cases of these colors, and in that event, I would recommend purchasing as many as possible. These colors include tan, dark tan, orange, lime green, medium blue, dark brown, and dark red. Again, these pieces may cost a bit more if you were to purchase individual pieces online, and if you happen to stumble upon them at a LEGO Store, fill up your cup -- because they won't last long!

Semi-rare colors are to be rationed, but not completely neglected. These colors are mostly slightly-varied shades of the previous ones, which in some cases you can actually mimic thanks to LEGO color mixing (which you'll ready about by and by). Sand red, sand green, sand purple, and sand blue are actually rather uncommon outright -- and medium azure is hard to obtain as well. Dark green, dark orange, medium dark flesh, and dark blue are pricey, although some can be slightly cheaper than others.

Finally, rare colors should be avoided if possible, due to their high value in conjunction with scarcity. For instance, even if you were to find a dealer online who has pink or purple LEGO pieces for under 20 cents U.S., he/she might only have a few in stock -- in contrast with standard colors like black or yellow, to which you can purchase hundreds for only a few dollars. The multiple shades of pink and purple only come in a handful of sets and are almost never available at LEGO Stores -- thus online dealers tend to jack up the prices for individual parts. If you're thinking about making a huge mosaic that requires a ton of pink and purple squares, you'd best be prepared to spend a lot of money and buy your parts from multiple vendors -- as opposed to choosing basic colors and getting everything you need at once and for a low price. When making my Chase McCain portrait, the reference photo called for several shades of blue -- and to cut corners, I reduced the colors in Photoshop, so that I could merely use blue and medium blue in his cop uniform -- rather than scrambling to find a bunch of Maersk blue bricks -- which run for about 35 cents a piece U.S.

If you don't have the luxury of living in a geographic region with more than one LEGO Store, the best place to obtain bricks would be from BrickLink.com -- which is essentially a candy store for new and used LEGO pieces. Any piece, color, or model you could ever want is available on that site via numerous vendors in just about every nation. You simply browse the catalog of which parts you need, then see if a certain vendor in your country has those in stock. You're able to shop around and compare stores to see who has the better deal, such as if one particular vendor has a greater quantity of a specific color than another store, but charges slightly more money. Using your own savvy of buying things online, I'd highly recommend checking out that site and becoming familiar.

Step 3: Preparing Your Image

This next part requires some knowledge of graphic design. I personally work as a graphic artist for a sports company in Long Island, NY, hence I have an advanced knowledge of Photoshop and Illustrator. Being able to use these programs efficiently is vital to preparing an image; otherwise, rudimentary software like Microsoft Paint can technically suffice -- albeit with more of a challenge. I'm going to present this entire section with the implication that you the reader has access to Photoshop, either as a regular edition or a trial; either way, some of these forthcoming techniques may sound rather confusing to the person who's never used an Adobe product.

After you've determined what image you'd like to use and what colors to make it -- or that if you're making a video game sprite -- make a new image in Photoshop with the canvas size rather small. As mentioned in the last step, a 16 x 16 pixel image will be equal to about 5.5 inches tall when built in LEGO form. My Nintendo Wii U logo for Nintendo World Store was 90 pixels wide on the computer, but was almost three feet wide in reality! If you've never assembled a large LEGO project nor a mosaic image, I wouldn't recommend tackling a huge portrait that exceeds 32 pixels in initial length.

Now, if you're using video game sprites, then congratulations -- this will be rather easy to prepare an image, for the sprites are already made of tiny mosaic squares, thus you won't have to do a lot of work. But if you're planning on making a vertical LEGO portrait of an original image, you'll have to prepare it via index coloring. For this example, I'll show you three index-colored photos: a video game sprite, a black and white photo, and a full-color photo -- all three are arranged in order of difficulty to prepare, from easiest to hardest.

Again, making a video game mosaic is rather easy, as the games themselves were blocky and pixelated, and contained mostly primary colors. A black and white photo is more elaborate, but has a reduced color table for easily acquiring parts. Finally, using a full-color photo converted to 120 pixels wide (120 pixels = 120 LEGO pieces wide = about three feet wide) with the index color table containing 33 different color options -- some standard, some rare -- with moderate diffusion. The diffusion meter (which is optional) controls the spreading out of pixels to maintain more accuracy of the base photo. With index coloring, your image is verbatim to the specific colors you apply to it; when using a full-color photo of Jonathan Frakes, with its colors reduced to 33 (and only a few of those actually being assigned), you notice the picture looks choppy and pixelated as if it's a poorly-optimized Gif image -- but, this is what we're looking for -- a blocky image with reduced colors! To make a picture in indexed color mode in Photoshop, select Image > Mode > Index Color, then at the top dropdown menu, select "Custom", and then load a color table -- the color table in the download links below, which contain the 33 LEGO colors I mentioned in the beginning of the tutorial, from standard to super rare colors.

Step 4: Constructing a Sturdy Base

Now that you've decided how big you want the portrait to be, what colors to use, and what image to build, it's time to make a sturdy base! Some mosaic builders will forfeit a base and simply make a huge portrait as is, whilst I recommend constructing a base for the entire picture to stand upon. The base is primarily composed of slope pieces in a pyramidal fashion, to prevent wobbling. I generally use black 2 x 3 and 2 x 2 slopes, as the LEGO Stores in my area tend to have them cheap in bulk. Making a base is pretty straightforward using the basic principles of masonry techniques for structural integrity. In this section you'll see a 3D model of a base; bases vary in size according to the width of your mosaic picture (I've also included a LEGO Digital Designer file of a 32 x 32 base in the bottom links). Again, a base is rather simple in construction, and merely requires basic bricks, slopes, and plates in a repeating fashion. The base can be as tall as you'd like, although I'd recommend it to flair out more on the sides if your picture is going to be big, as the flaring will prevent wobbling. If your picture will be taller than 40 LEGO bricks, it's almost imperative that your pyramidal base be at least three tiers high of slopes (the particular 3D illustration is two tiers high, and 32 studs wide at the top with minor side flaring). Also keep in mind that the top of the base must be the same thickness as the the portrait you're making; this particular sample base has a thickness of two LEGO bricks -- thus, the base for this portrait would be 32 bricks wide, 2 bricks tall, and 2 bricks thick.

Again, a base is not mandatory -- but highly encouraged if you want your final portrait to be a stand-alone structure. If you want to incorporate your mosaic wall into a preexisting structure, like a ship or a castle, then ignore this step, and simply use the remaining steps to make your portrait however you please. I've actually done both: my mosaic portraits commissioned by Nintendo World Store were stand-alone pictures for the display case, whilst my giant Super Mario 3 airship had vertical mosaic walls for the inside of the ship's cabin. As you can see in the image of the stained-glass window fire flower sprite, that particular mosaic didn't require a base, as it was integrated with the structure of the ship itself.

Step 5: Using Your Reference Photo

Alright, folks: at this point you've chosen a photo, acquired a ton of LEGO pieces, prepared your image in Photoshop (or a similar program), and constructed a base. Now it's time to use your reference photo for laying out each layer! By now, I'll assume that you have a computer right next to your LEGO work station and/or table, since it's required to glance back and forth at a monitor as you assemble your mosaic. Lucky for me, I have a laptop, hence I've got it opened up next to my side at my table in my workshop. If you don't have the ability to scoot your computer around, I'd recommend trying to move your table up against your computer, or try to figure out a way to assemble your mosaic on top of your computer desk with your monitor in plain sight. Regardless of what you do, the following section is specifically geared towards the assumption that you've got a computer nearby!

In Photoshop CS5 on up, when zoomed in far enough into an image, a grid appears over each pixel: this is extremely vital in counting pixels and figuring out where each LEGO piece will go. I also prefer to make a top layer of a solid color that covers up the image, and after I've completed an entire line, I move the whole color layer (the purple layer in the example photo) up one pixel at a time, to avoid confusion. You can also hide the layer any time to skip ahead and see what the next line's colors will require, in case you'd like to jump the gun and do any special masonry techniques to ensure durability. For instance, when making that Mario warp pipe on the far right, the straight line pixelation made a horrible masonry pattern that was rickety -- thus, I skipped ahead to the black line in the middle (above the Kirby star wand, below Mega Man) and assembled the black line the whole way across to keep the green lines in place. You're free to move the guide anywhere you'd like, but to remember which line you're currently working on, make sure to have your Photoshop rulers visible and use the guide lines to mark spots.

Step 6: Quit Slacking - Get to Work!

As you can see, my most recent vertical mosaic portrait was a composite image of various Nintendo sprites from the 8-bit and Game Boy era, and had a thickness of two LEGO bricks -- with an overall width of 120 bricks (not counting the flared base, which was pyramidal and five bricks high). At this point, you've got your image ready in Photoshop, the colors are all indexed and whatnot, you're zoomed in to specific pixels, you have a ton of assorted LEGO pieces all around you, your computer monitor and/or laptop is at your side, and you've got a playlist of 1980s hits on a constant loop as you press down on these little plastic toys for several hours straight!

Where applicable, always be sure to use a sturdy masonry pattern: in other words, try to as often as possible make your top layer of bricks overlap over the cracks of the previous layer. This is a major issue when you're doing super detailed stuff with individual 1x1 pixels -- as you can see in the far right warp pipe. As with the warp pipe, I had no other option but to not have the pieces overlap, hence that particular section of the completed mosaic is kind of weak and wobbly -- unlike the area with Samus and Bomberman, which is quite strong.

Step 7: Tips & Tricks

1) With the magic of making a vertical mosaic -- as opposed to a horizontal one -- you can actually blend colors to make new shades and or/substitutions. As shown in the first image, I made a pale green color to mimic the Game Boy screen by alternating tan and lime green plate pieces. Also in the Duck Hunt duck's bill/feet, I weaved tan and orange, as I did in the Ice Climber's skin. I did a checker pattern of orange and dark medium flesh bricks for the bulk of the Mario coin block, with the question mark symbol being made of alternating horizontal lines of white and yellow, to create a paler yellow color. As you can tell, towards the top the sky gets gradually darker before dissolving to black: I had gradual blending of blue and dark navy blue, before introducing black -- thus creating a gradient illusion. Mixing colors is an invaluable technique if you don't have a certain color available; take for instance you're trying to make an accurate pale skin color, you could weave red, white, and tan plates together, akin to a retro comic book where colors where limited and people's skin tones were made of white backgrounds with tiny orange dots (think Roy Lichtenstein's Crying Girl).

2) Never bite off more than you can chew! No no no, wait, wait, I'm not referring to biting bricks -- because that's an asinine thing to do -- rather, I'm speaking about tackling huge projects if your skills are dull. In other words, I'll give you the completely honest, blunt truth -- which may come off as a bit pretentious and condescending to some of you more novice builders: if your only source of income is earning an allowance, the largest LEGO set you've assembled was that Harry Potter set you got for Christmas (and built with the help of your parents), and you don't have access to Photoshop, I would NOT -- I repeat, I would NOT recommend taking on a huge, ambitious LEGO mosaic that contains dozens of colors and thousands of pieces! Trust me, you'll only frustrate yourself and diminish your wages in the process. In this case, I would highly encourage you to only build what you're capable of doing with the pieces/colors you've already got. To start off, try making a simple 16 x 16 mosaic portrait of a retro gaming sprite, which only uses basic colors. Once you've practiced enough and got the gist of making mosaics, then feel free to work your way up to larger images and more elaborate designs. I could be wrong: you, the reader could be filthy rich and have experience with bricklaying as a profession, hence you could easily afford to throw down a couple hundred bucks here and there to buy parts and make a durable LEGO mosaic portrait. I could be wrong, I could be right. I will, however, point out that making elaborate mosaics can be increasingly difficult, not to mention frustrating when you run out of a specific color and have to keep buying more pieces. Only work within your means, from not only a financial standpoint but also a creative one too; never do something you're uncomfortable with doing, and to save yourself the stress, start off small and simple as a form of practicing. The first vertical mosaic I ever constructed was the inner cabin of my Fireflower Airship, which used simple 16 x 16 pixel walls of Mario sprites. I ran into no real challenges per-se, but then used that acquired skill to make my larger portraits for Nintendo World Store in April 2013. From there, I had the experience and talent to create the giant 120-piece-wide Nintendo character portrait as shown in this tutorial.

3) For tools of the trade, LEGO actually produces a device called a Brick Separator. This simple and cheap tool uses basic leverage functionality to pry pieces apart. I've personally got three of 'em, although I'll let you in on a little Baron von Brunk secret: I grow my fingernails really long so that I can easily pick apart pieces! Some of you younger male builders might have uptight parents that would get concerned about you growing your nails out, but if they ever ask, just tell 'em you're learning how to play classical guitar or something. I've consistently maintained long fingernails since childhood specifically to easily pry apart my LEGO models; it's one of my quirky traits that a lot of folks don't quite understand when they see my fingers up close (what's even worse is that my speaking voice is naturally really fast and jumbled, so occasionally people who will hear me talk rapidly will then stare at my long nails and get a false conclusion that my nails are used for ill purposes, if you catch my drift). But anyway, yeah, get yourself a brick separator or at least stop biting your nails for a while, because you're bound to make mistakes when putting these things together! Nothing's worse than trying to assemble a 1,000+ piece LEGO model and your dexterity is totally shoddy; your fingernails are like nature's needle-nose pliers!

4) I almost never glue my LEGO models together, however if you plan on gluing yours, I'd recommend a soft glue that doesn't immediately dry, in case you need to make changes in bricks. You'll frustrate yourself to infinity and beyond if you glue each piece in with Krazy Glue and accidentally made a mistake. Your best bet is wood glue or school glue, which are both gooey and take a while to dry; with those glues, any errors in placement can be easily resolved, as long as you're quick enough and make sure to wipe off the glue.

5) Building custom LEGO models is a non-union gig -- thus you can drink on the job! Assuming you're over 21 and currently residing in a place that's not a fascist state, feel free to consume beer whilst assembling your vertical LEGO mosaic! In my case, Coney Island Lager's Mermaid Pilsner was a vital addition to my construction. Beer can be purchased at your local 7-Eleven store, along with donuts and nachos. However, try to avoid foods that could make a mess when touching your LEGO pieces (i.e. Doritos).

6) Put on a playlist of '80s new wave and pop to relax yourself as you build these things. I'm serious. When you really delve into these vivid projects and zone out into your own private world of multicolored plastic bricks and British one-hit-wonder synth songs, everything else around you disappears. When I'm "in the zone", I no longer care about taxes, work, obnoxious roommates, sore fingertips, and the absurd hatemail I keep getting on OkCupid. Oh, if you've got a smartphone and Instagram, be sure to occasionally snap work-in-progress photos to give something neat for your friends to check out until your creation is done!

Step 8: Epilogue

Sleep tight, kiddies, and remember: if you have a problem, if no one else can help -- and if you can find him, maybe you can hire. . . The Baron!

I make a living creating custom LEGO portraits at Brickworkz Lego mosaics and am really looking forward to trying your directions on a vertical style mosaic. Adult fans of LEGO often call this a "Studs Up" technique and the type I typically do is Studs-Out, or more fun: Studs Not On Top (SNOT) hehe - You end up getting higher quality with the vertical Studs-up style when using LEGO plates than you can in the same space with SNOT style, but there are structural considerations to make for sure! I'm sure things get wobbly as they get taller.

When I read your warning:

"I would NOT recommend taking on a huge, ambitious LEGO mosaic that contains dozens of colors and thousands of pieces!"

I thought I'd let your visitors know that if they bite off more than they can chew, feel free to visit my site and I'm happy to consult with mosaic builders!

I think your best recommendation is about us being non-union! Drink up! ;-) Great write-up. Thank you for posting!
