I was surfing the web the other day when i came across this crazy illusion. Enable it in fullscreen if you can, and stare into the center until the video ends, then look around the room. Everything should be distorted for a short time! Does anyone have an idea of why this happens?UPDATE: Goodhart kindly mentioned that this video should not be viewed by anyone with epilepsy, as it could bring on a seizure.

 Heeeelllloooo!So i just wanted to talk about my group Optical Illusions,and yes I know it looks like there is 3 I's but it's actually 1I and 2L's.This group is about magic or DUH optical illusions.Ibles and videos must come to me before published.I will post updates every Tuesday,Friday,or Saturday.If I have time any other days I will update.My only rules are if you try to post a bad video I might give you a warning first but the second time you try I will kick you out.Well that is all you need to know.Oh wait one more thing...I will change the picture every month. 

Here is an awesome wall art illusion, it took me about 2 hours to do as there was alot of tweaking involved. Hope you like it and tell me what you think.

After posting about the 50 papercraft robots I couldn't help but print out the robot dog illusion and make it. After all, it's a robot dog version of the dragon illusion that I've been meaning to make for years now (and still haven't). It only takes a few minutes to put together so check it out. SuperRobot Dog Version!

Does anybody know why this works, its so cool! Stare at the 4 dots in the middle for 30-40 seconds, then look at something like a white wall. Then blink, what do you see?

How many animals do you see?

Here is a cool optical illusion I got in an email:'The Brain'This is quite amazing..If you see this lady turning in clockwise you are using your right brain. If you see it the other way, you are using left brain.Some people do see both ways, but most people see it only one way.See if you can make her go one way and then the other byshifting the brain's current.BOTH DIRECTIONS CAN BE SEENExperimentation has shown that the two different sides, or hemispheres,of the brain are responsible for different manners of thinking.The following table illustrates the differences between left-brain andright-brain thinking:Left Brain Right BrainLogical RandomSequential IntuitiveRational HolisticAnalytical SynthesizingObjective SubjectiveLooks at Looks atparts wholesMost individuals have a distinct preference for one of these styles of thinking. Some, however, are morewhole-brained and equally adept at both modes.In general, schools tend to favor left-brain modes ofthinking, while downplaying the right-brain activities.Left-brain scholastic subjects focus on logical thinking,analysis, and accuracy. Right-brained subjects, on theother hand, focus on aesthetics, feeling, and creativity.If you look away, she may switch from one direction to the other.I found that if I just look at her feet or relax and look at the floorwhere the reflection shows, she will switch direction!

My instructable is . how to make a optical illusion

I visited the sculpters shop in manitou springs colorado micheal gorman there is an unbelievable display called magic town, in the model building have scenes within the building which change between two scenes there appears to be a glass panel, at 45 degrees some of the objects in the scene are attached upside down and when the scene changes they appear in the next scene there are small light bulbs which go on and off as the scene changes his is not a good description but can anyone explain to me how this is done its driving me crazy

I found an image with the length dimensions for the Rooftop Illusion but cannot find the angles to allow us to actually build it to work...can anyone help?

The video below was awarded Best Illusion of the Year at this year's Vision Sciences Society meeting.  I originally saw this posted in Nature News: In a packed concert hall, Kokichi Sugihara wields a pickaxe and mimes a blow to the stage. "I am a miner, and I have a secret," Sugihara says, adjusting his hard hat and headlamp. "I have discovered a new super-magnet." A screen behind Sugihara begins playing a video. A cardboard structure appears, consisting of four ramps ascending to a raised platform. A hand places a wooden ball at the base of a ramp, and it rolls uphill, before stopping on the 'super-magnetized' platform. As the same trick is repeated for the other three ramps, the crowd lets out an "ooh". Thanks to Kiteman, here's the author's own Web site: http://home.mims.meiji.ac.jp/~sugihara/hobby/hobbye.html Image and video from Koichi Sugihara, Meiji University.

I'm planning a mystery dinner party. There will be a postage stamp on display. I have a way to trigger a lights-out remotely (just by plugging the lamps into a remote-control switch). During the blackout, which will last a few seconds until I can "find the fuse box," the stamp needs to disappear. I could of course just walk over and steal it myself, but I'm looking for other suggestions. Print the stamp with some kind of ink that will vanish if hit with a camera flash? Some sort of motor-and-string attachment that could pull the stamp into a hidden chamber in the display case?

The new advertising is a little longer, but a little more entertaining as this short video is a good example of. I don't care much about getting a new phone, but kudos to Samsung for making a playful video that compiles some classic optical illusions.via Techeblog

READ THE DESCRIPTION FIRST IT HAS THE INSTRUCTIONS!One of the freakiest illusions ever! Basically what you need to do is listen to this with your EYES SHUT and with headphones or earphones: NOTHING ELSE, otherwise it will not work. Oh and you need to have the earphones/headphones plugged into both ears, not just one. This is basically designed to give the illusion of having a haircut, but it REALLY WORKS!

Check out the optical illusion below. Since the figure is totally black, there's no depth- you can see her spinning either clockwise or counter-clockwise. Which way do you see it first? Try reversing the spin direction- moving your finger in a circular motion at the rate of rotation can help you reset. How easy is do you find it to swap perspective? Does it make your brain hurt?

I saw this video on Facebook which shows a Ouija board themed cake with the planchette hovering aboard the cake surface and spinning.People have asked how this is done, but the maker is not answering.It looks to me like it must be magnetic. I don't really care about cakes, but it would be cool to make something that levitates and even spins like this. A "haunted Ouija board" would be an obvious application fro a haunted house. So, how would you duplicate this effect?

I'm interested in building a box to perform this illusion on the relatively-cheap. Granted, there are many ways of performing this illusion; I'd like to build one that doesn't require two women but uses fake legs instead. I don't need help with the fake legs.

Here's a very cool illusion I have taken from this BBC article. First notice that the two desert scenes have exactly the same colour composition. The skies are both blue-ish and the deserts are both yellow-ish. Stare at the dot between the red and green squares for 60 seconds, and then look back at the dot between the two desert scenes. The more focused you are in staring at the dot between the green and red squares the better the subsequent illusion will be. The illusion was created by neuroscientist Beau Lotto (website here, with more illusions). (Are you colour blind?  Do you see any effect from this illusion?) I have a feeling that this effect could be used in some sort of cool Instructable, but I have no idea what...

I am a carpet manufacturer based out of Agra (India) and I have been quite captivated by the magic of scanimation. I have now been thinking of making a series of carpets in scanimated designs and using a coffee table with black printed stripes in lieu of bar mask. (This idea is not mine, please see http://www.youtube.com/watch?v=Ua7HOX32PGA … I have no intention of copying it , but taking inspiration from him I wish to take this to a whole new level) I want to know, if this is possible in only black/white or can we use more colors as well. For example, maybe I can have 5-6 turtles with their legs in black , the background white and the turtle’s body in color. Will then I get the effect of movement ? Could someone help me in preparing some designs ? 

So I was considering going as Nickola Tesla for Halloween and showcasing his ideas as sort of party tricks...like a Tesla turbine blade and whatnot. But seeing as he is primarily known for electricity work, I thought it would be cool if I could somehow come up with a way to make a lightbulb glow while holding it. I tossed around the idea of running a powersource to a conductive glove to power it and also of making a self contained powered bulb but not sure. Any ideas on how to make some sort of electrical phenomenon illusion? Thanks.

How do you watch a private video as in this link?: https://www.instructables.com/id/30-Second-Optical-Illusion-Solid-Through-a-Solid/

Here is an awesome illusion that took me around half an hour to make and film and edit. Enjoy =)

Has anyone ever made a motion lamp. I thing the rising heat from the bulb or candle made the inside rotate giving the illusion of motion

Every year I have a huge Christmas party at my place, and every year I do something more over the top. I'm just now getting into lighting and things and have no background experience in any of this. For instance, you say relay switch... I say WHA? I of course can "look it up", and I've been known to dabble in circuitry. However, I wanted this year to try to re-create the singing halloween pumpkins (that I saw in a video), or the singing Haunted mansion ghosts, into singing animated ornaments (the big kind). I know this can be done, its just a matter of understanding the steps involved. For instance, I know I will probably need a projector of sorts and huge ornaments and some sort of animation. I mostly have mac products so if the programs are for windows they won't work for me. Also, the easiest will probably be the best since I'm new. I also checked out the hologram illusion technique and the glass projection as ideas for doing this or possibly showing a floating movie or christmas short. Thanks for any and all highly detailed information. I would love to get into these things as I'm a Christmas nut and well, most of the Christmas stuff out there just sucks for creativity, but Halloween decor is insanely cool.  I want Disney-like animations and projections. Something special that WOWS. Thanks again!

I really like this television show. The masked magician show how to do great tricks and illusions. I even did some at school. Like levitating, walking on water, cutting someone in half and the wine and needle trick. Do you like it ? or what do you think ?

Traffic calming schemes are frequently unpopular with drivers; speed bumps and oddly-placed bollards make life uncomfortable. In Norfolk, England, a new scheme is being presented that slows traffic without even touching the road or obstructing the driver. Two hundred trees have been planted at the boundaries of villages suffering from speeding drivers, and it is the trees that fool drivers into slowing; they are in rows down each side of the road, and as they approach the village, they get slightly closer together, and slightly closer to the road. Seen only in the driver's peripheral vision, the trees give the same subliminal visual clues as increasing speed would, and drivers respond by unconsciously slowing down.  The illusion has slowed traffic by an average of about 3km per hour. The illusion has been used before (rumble strips on the approaches to roundabouts are spaced more and more closely together to create an audible illusion of acceleration), but the more subtle nature of the tree-planting makes it less obvious, and thus harder to resist.  Provisionally seen as a success, more detailed, longer-term results are to be presented to the Department of Transport in the Autumn, with a view to rolling it out on B-roads nationally.

I have been cast as Merlin in a medieval fair living chess board act. We have a few reliable magic tricks we've used in the past, but I'm trying to find/think up new ideas. This is a live show and I will most likely be standing on an elevated stage for most of it. I don't mind cheesy tricks (I might even do the string of handkerchiefs up the sleeve gag). Illusions that can be used in "combat" are very welcome. So, if you have ideas, or know of any websites that will help, I'd really appreciate. I've looked through Instructables, but haven't found much, so if you know any good ones, assume I missed them.

I have found a model of eschers waterfall on "think geek" but i appears to have sold out. does anyone know where to buy a new/used model of it? under £60 pounds would be perfect!!!!!!

I have an instructable about designing better reflectors for solar cookers. (Better than parabolic dishes). Basically you can design your own dish, and compare it to the parabolic dish and other shapes with the software. On step 1 there is a zipped folder for download. It contains an art of illusion scenefile. Art of illusion is the modeling and animation software I used. It is easier to learn than its competitors and it is free. The folder also contains a html file for almost automatic tabulating of your results and comparison with other reflector shapes. I have "starter" jpg images for when you create series of 10 images for comparison. I hope to put in a help html file too but thats all for now. To test it, you do need to download art of illusion too. I know this type of project can be a bit of a pain but with feedback, I can refine it. And where else do you have free tools to test solar reflectors? https://www.instructables.com/id/Use_software_to_design_a_better_solar_cooker/I hope that this will grow. A guy in Finland has already done a rudimentary "sun engine" that will do the shadows from a day as an extension to this project! That could be used to design passive solar houses and to site vegetable and fruit gardens in the best spots. (Depending on the seasons and day length, shadow patterns from trees and houses are very different). This is not something you can imagine just from surveying a site! Anyway, hopefully I will get some input.The instructable has grown and changed a lot as I have improved the scenefile. There are certainly parts that need trimming now. Hopefully I get round to it in the next couple of days. Brian

When in Europe, I saw a street vender that stood near his little boom box and had 2 dancing paper dolls next to it. I bought the paper dolls and now need to figure out what he did to his speakers or magnets in his speaker to create this illusion of dancing dolls that can dance next to a boom box. The dolls had magnets on the backs of them, so it had something to do with a magnet inside his boombox. Can you help? Thank you.

So for Halloween I want to make a pop out/ fly out creature. I want it to sit tucked away in the corner then shoot out two to five feet towards unsuspecting guests, to give the illusion of something flying out at you. I was thinking of doing the scissor (http://www.frightprops.com/pneumatics/kits/animatronic-kits/horizontal-scissor-mech.html?SID=d3f43bbaffe0a34f01e47e75eade4e39) but need to figure out how I'm going to be able to make it repeat over and over without having to reset it constantly. If you have any ideas please email me.?

Parabolic dishes are favoured because they are "perfect". Unfortunately they are only perfect if they are kept constantly pointed at the sun. In practice this is very hard to do. A better shape would maintain good reflection of the sunlight for a long time without moving the dish.I think I have found useful easy software to help with this design work. It is called art of illusion and you can see my first results and a downloadable scene file to help you get started on step 12 of this instructable https://www.instructables.com/id/Make_a_quotcompoundquot_parabolic_solar_cooker/Brian White

Hi there! I have successfully been making some LED hula-hoops but my ultimate challenge lies before me: I want to program colour-changing LEDs so that they pulse ultra-fast and appear 'white' when at standstill but leave rainbow trails when they move. I believe it to be an optical illusion caused by the pulsing... I assume this requires a PIC program but I have no idea where to start or even if I am on the right track - does anyone out there know how I might achieve this? thanking you in advance, Amelia

I've been thinking aout making a portable game player/computer, like a Game Boy or PDA, and I think I can handle most of it, except the screen. I don't think I'd be able to easily make my own, and I don't seem to be getting very good results searching on Google (usualy I just end up finding monitors for desktops and devices with screens built into them). I'm looking for anything with at least 64X32 resolution, two colors (black and white maybe?), and enough frames per second to create the illusion of motion. More important, however, is that it should either via standard PC serial port or USB.

I'm using: 12V supply, 3mm or maybe 5mm blue leds 3.1v (20mA) (288 pcs) 470ohm(?) resistors(288pcs) I want one led to light and stay lit, then I need a 6 hundredths of a second delay before 2nd led lights and stays lit then delay and  third light, and so on, and so on. All lights to remain on  as it goes... and until completed... then all off in order to begin a new cycle. (Approximate cycle time is 20 sec to light all 288 leds) Trying to create the illusion of handwriting with leds.What capacitors and other resistors do I need to cause the delays?  Wiring diagram plz. I'm a newbie. What size Fuse and its location? Thanks for not slapping me around to much. And thanks for helping.

Hi everyone, Take a look at the illustration attached.  Is there any real difference in values between the four winding types? *** Assuming same core, same wire gauge and same number of windings on all 4 primaries, and all 4 secondaries *** A) Both primary and secondary are wound TOGETHER. B) primary is wound first, then secondary wound ON TOP. C) Primary and secondary are wound at OPPOSITE SIDES of the core . D) Primary and secondary are wound next to each other on the SAME SIDE of the core. Note that figure in D it seems like the wires are thinner, but I assure you, that's an optical illusion, and the gauge is the same in all 4 figures :-p Again, the question is whether the 4 coils would act the same in a circuit, or is there a difference in values between them? Thanks!

I'm looking to create a hinged leg to use in a "Jake the Peg" Halloween costume prop. If you've never heard of Jake the Peg, here's a link  to the famous Rolph Harris skit. I know he's using a false hand on the right side (his right) so that he can control the extra leg, but I'm unsure on how to create the hinged effect. (It's the bending of the leg that makes it so realistic!) I was thinking of using something like a bike handlebar end with a handbrake lever to pull a cable that would draw the leg up, but how would I get it to spring back to the straight position? (And when it's in that position, it would need to support some weight like a cane) What should the leg be made of? There has got to be a better way to do this. The illusion is fantastic, but there are no articles anywhere on how it is done. Thanks for any help anyone may have.

I recently bought some resin that I was going to test a few prop pieces out with, but, being the space cadet I am, did not pay attention to the volume the resin produces, and I'm now short resin. I can, of course, buy more resin, but I had the idea of kind of cheating and just coating the inside of a coke bottle (the glass ones) with the colored resin and filling it with water to match.  Also, there is more to this. I know I can color water and fill the bottle with that to make a colored bottle. I also know I could color the resin and fill the bottle with that. However, I have an additive that I want to use that is rather pricey, so I would only like to coat the inside of the bottle as to give the illusion it is filled with liquid instead of actually filling it up with liquid. thanks in advance! 

I am a filmmaker and one of the things I adore is special effects.  One of things I want to do is make a simple effect in which I use a real physical model of a vehicle and I put it in front of a green screen.  However give it the illusion that a camera is panning around the whole thing while it's driving through whatever background I put in place of the green screen.  The way I want to do this is to make a swivel which on one end has a small green screen rigged on one end of the swivel and on the other end of it, a camera that is lined up with it. So that when I turn the swivel the camera would always follow the green screen. So that when I edit it in effects it would look as if whatever is in front of the green screen is traveling along an endless background while the camera is panning around the object.

Some quite unbelievable art by artist Li WeiChinese artist Li Wei creates art that proves to be impossible. How does he do it, you ask? Performance art and photography is what creates these dangerous illusions. He also uses props such as metal wires, mirrors, scaffolding and acrobatics to help him with the effect.This art is a series of self-portraits that he has made that uses mirrors to reflect his image. Some of his photos sell for around $8,000. As for what people around him think, he told Daily Mail, "The first reaction is astonishment. Some people think they are full of sense of humour. They are curious about how I did this. Sometimes I am in real danger - I have to hang myself high with steel wires and people do get a little worried for me - but I am fine."link via inventorspot.

Ever done your first Instructable and then not to have had much interest from others? Never really wanted to tell every one about it because that might be considered as "Advertising"?Well, firstly, it's not advertising if it's not obtrusive and secondly, you're in the right place!Post here the first of your many Instructables to come, give it's title, a brief description, a picture or two and a link. There's no prize (from me) but you will get a lot more views than previously.Here's mine, it's a simple optical illusion that's not too hard to make (if you know how) and is an extremely easy way to make money at school, when people start asking "Can I have one?" and "Can you make me one?" Just remember, feed back's always nice, comment on every one else's; they might comment on yours.Hope to see yours!~K

Hello,I was just wondering if anyone could help. I have an idea for something I want to build, however I just need a push in the right direction.I’m working on a costume with antenna ears. I could just make them static however I want to add a bit of movement. Basicially I want them to, when I tilt my head down, the ears flatten (think a cats ears when angry) and when I lean my head back, they point up. The rest of the time they stay in the middle.I want them to be automatic. I really hate triggers or controls, as soon as someone notices how you are operating it, the illusion is ruined. I also don’t want to use electronics (the sound of a motor).I am absolutely sure I can oull this off, however I’m not sure the best way of doing it. I was thinking fluid filled tubes, as the water exits one it enters the other. Or the mechanism in dolls so they sleep while lying down.Does anyone have other ideas or pointers?

Anthony Le is such a fan of Iron Man that he built his own War Machine outfit. Based on concept sketches from before Iron Man 2 hit theaters, Le's suit has a motorized faceplate that flips up and down and a spinning Gatling gun on his shoulder. It's an amazing build and took Le a month to make at a cost of $4,000. Great job! Le, a fitness consultant, studied some concept sketches of the suit posted on the Internet. He used thin, high-impact urethane for the armor, cutting it into plates and joining them with some 1,500 rivets and washers. He sculpted a clay helmet mold and then used a liquid resin mix to create the final product. But that was just cosmetic work. He also added a small servo motor that opens the faceplate, as in the movie, and built a gun out of pipes and a motor. LEDs in the eyes and chest-plate further add to the illusion. You Built What?!
