Introduction: Princess Peach Pointillism

About: Mad scientist, woodworker, creative evil, artist, tinkerer, father of five creative hooligans.
1080 980 plastic bottle caps + 16 acrylic paint colors + a couple of Perl scripts + 6 months worth of work =

Step 1: Materials

First, convince your entire family to start collecting plastic bottle caps. To make things even more fun, don't tell them why they are collecting caps.

Select a suitable picture, in my case I selected a 30 x 36 image of Princess Peach. Be sure to select a small image as you're going to need one cap for every pixel.

Once you have collected at least 1080 caps, you're ready to start phase two.

(Note: It's been pointed out that the image is actually 28 x 35 totalling 980 caps. I forgot that I lost a row and and two columns when I  planned out the border. Small oversight on my part, can't believe someone actually counted!)

Step 2: Color Selection

I used some Perl code and ImageMagick to extract the color pallet from the image. For each color in the pallet, I assigned a simplified hexadecimal code:

$cc{"000000"} = "0"; 000000 = 237
$cc{"A85000"} = "1"; A85000 = 6
$cc{"B81018"} = "2"; B81018 = 5
$cc{"D03850"} = "3"; D03850 = 32
$cc{"E86000"} = "4"; E86000 = 47
$cc{"E86050"} = "5"; E86050 = 8
$cc{"E08030"} = "6"; E08030 = 3
$cc{"E88090"} = "7"; E88090 = 29
$cc{"F09058"} = "8"; F09058 = 42
$cc{"F0C830"} = "9"; F0C830 = 9
$cc{"F8A800"} = "A"; F8A800 = 117
$cc{"F8B0D0"} = "B"; F8B0D0 = 40
$cc{"F8B880"} = "C"; F8B880 = 23
$cc{"F8F030"} = "D"; F8F030 = 60
$cc{"F8F8F8"} = "E"; F8F8F8 = 35
$cc{"FFFFFF"} = "F"; FFFFFF = 387

Total = 1080

The program output above shows the color code in hex, its assigned simplified code, and the number of times that particular pixel appears in the image.

I then created a pallet chart and printed it out. When mixing colors, I would first test them against the palette. For me, mixing a large amount of the same color was challenging.



Step 3: Painting the Caps

Using the printed color pallet, I then hand-painted each cap with acrylic paint. For example, I painted 237 black caps, 117 orange, etc. Painting the caps was tedious and time-consuming and I had to “develop” a special tool to help with the painting process. I used a 3/4” wood dowel with painters tape around one end. The caps fit snugly on the end of the cap so they didn't fall off while painting and then easily popped off for drying.

I opted to not spray paint them because I wanted to mix my own colors and ensure an even coat on the surface of the cap. In hindsight, an air brush may have been a better choice.

During the painting process, I made some modifications to the overall design and decided to change the boring white background on the original image to something more visually appealing.

The entire painting process took about 6 months working on and off.

Step 4: Layout

Keep in mind that up to this point, no one had any idea what I was making. We were collecting and painting caps, but the overall image was not clear. Using the color codes assigned in the previous steps and another Perl program, I generated an image showing the location of each color code (like a paint by numbers set):

----000000000011111111112222222222

35: FFF00000F00000333000333000FFFF

total caps needed: 1081;

If you squint, you can almost make out the image in the letters and numbers above.

It was at this point that I realized just how big this picture was going to be. Each cap is roughly 31mm in diameter. Given that all caps are a little different, I set the grid to 33mm squares. The final image ended up at 3 feet wide by 4 feet tall! Not exactly something you can keep on your desk.

I cut a piece of melamine large enough to fit the image and a 1 square wide border around it. Using a ruler, I marked out the grid and wrote in the values for each square.

I recruited my kids to help with the initial layout of the image. I had them start with the black caps and asked them to guess what the picture was. Half-way through the process, my fourth daughter shouted out, Peach!

Step 5: Final

When I had almost finished painting caps, we sold our house and moved. I carefully packed up each cap (so they wouldn't be scratched) and crossed my fingers. Luckily, the entire project made it through the move in tact.

The final step was to build a frame. I build a simple wood frame out of pine with half-lathe corners and routed the back for the melamine to fit into. The frame is held together with wood glue and 1/2” brads.

I then carefully glued each cap down to the board using PolySeamSeal All-Purpose Adhesive and Caulk. This was a time-consuming and tedious process.  The caulk went on white and dried clear which made it easier to remove from surfaces where it didn't belong.

Overall, I'm pretty happy with the result. We took Peach out on the front porch and then went down the street to see how far away the image resolved. It was like having a giant icon on my porch!

    Congratulations on being featured in the magazine Nintendo Power!

    So I went out and bought a copy of Nintendo Power. Thank you so much for pointing that out. My kids think I'm famous. ;^)

    You most definitely are, amongst the 10 year old boy set!

    Wow really? Which issue number? This is news to me!

    How could i do this with beer caps? Using the original paint on the cap?

    Check out my other project: https://www.instructables.com/id/Dragon-Scales/

    The challenge is getting enough caps with the same or similar colors.

    Saw this in Nintendo Power!!! Awesome!!!!!!

    does any one know where i can just paste my image in and get a layout like in step 4

    Someone suggested this below: use Gimp or some other image manipulation program to save the file in XPM format. The result is almost the same.

    This is how i did it with Gimp (and im a total noob too so it took me a while to figure it out):
    Paste image into Gimp
    Image -> Mode -> Indenxed (dont change the options) -> ok
    Windows-> Dockable Dialogues -> Colormap
    Windows -> Docable Dialogues-> Histogram

    The number of the color on Colormap (ex: color index "x") is equal to "x,x" on the Histogram left and right boxes

    awesome

    How good did the paint hold? Acrylic to plastic in my experience holds very poorly.

    7 replies

    The paint holds ok, but it scratches easy. I need a good flat acrylic sealant.

    Couldnt you use a simple glue spray like elmers spary adhesive and let it dry? Or modge podge with a brush?

    What's modge podge? Does it have a glossy or matte finish?

    Just goto walmart and get yourself some Krylon crystal clear. They have satin, gloss semi, gloss

    Yes :D

    Its a puzzle saver glue. I noticed Elmers has a "spray adhesive" that might have the same effect. The only problem I can see with the modge podge is it doesnt have a spray form.

    Mod podge won't stick to plastic. And if you want to spray mod podge you could dilute it and use an air gun. I do that on my acrylic 3d wall art to seal in the paint.

    maybe Shelac? Just thought of it.  My grandma used it for pumpkins and gourds for holidays. I think any thing thats spray would be okay cause its a thin layer and as long as its not haldled so much it shouldnt chip right? I dont have a spray gun so your idea, though it sounds like its efficient, wouldnt work for me :(
