Something about how seeing is not believing

Every year, the Neural Correlates Association announces the world's three best optical illusions. Out of a number of finalists, the 2014 winners have been announced: 1) The Dynamic Ebbinghaus, 2) Flexible Colors, and 3) a Turn in the Road [animated gif version]. There are also a list of best illusions from all years, as well as winners from 2013, 2012, and previous posts. Of course, if there was a lifetime achievement award, it would need to go to Akiyoshi Kitaoka, inventor of some of the most amazing recent illusions: rotating snakes (seriously, this is amazing), possibly the best color illusion ever (with instructions on making them), and also Lady Gaga covers. Also, for no good reason, here are 20 more good ones.

"Whoa! That was crazy!"

Through the power of clever editing, forced perspective and some other subtle tricks, Zack King has a "magic" Vine compilation that is excellently entertaining. [slyt]

I Can Figure This Out

Naya's Quest is the new game from Terry Cavanagh. It looks like a simple isometric-view platformer but every level (once the game proper starts) is essentially an optical illusion. It will do your head in. In the best possible way. [more inside]

The Wheels On The Page Go Round And Round

Cat responds to rotational optical illusion. The illusion in question. But why does it work? Link to the actual paper.

A Watched Clock Never Moves

Have you ever wondered why you don't see motion blur when your eyes flick to a new position? Why, if you sit in front of a mirror and watch yourself, you never see your eyes move? That is saccadic masking, one of the lies your brain tells to avoid confusing you. Have you noticed that the first tick after glancing at a clock with a second hand can take more than one second? No, it's not just you! That's a related phenomenon called chronostasis, or more commonly the stopped clock illusion.

Bowerbirds: intentional architects, and accidental farmers

Bowerbirds, a family of 20 species in eight genera, are a fascinating bunch of birds who range from New Guinea and Australia. Some are flashy, others drab, but all are named for the "bowers" (avenues, huts, or towers of sticks; source) that the males craft and decorate to attract a mate. There are regional styles (PDF) in the design of the bowers, and the male Greater Bowerbirds even employ optical illusions. Some, like the Vogelkop Bowerbird, add mimicry vocal to their repertoire of courting methods. Add accidental cultivation to the list of fascinating features of the bowerbirds. [more inside]

Floating Water

Making water appear to levitate usually requires a strobe light to trick the eye. If you don't have a fancy system to control water flow, you can run water through a tube taped to a speaker playing very low frequency sound, and again use a strobe light to make the water appear to defy gravity. Or you can ditch the strobe, and sync the sound waves to the frame rate of a video camera to make water drops appear to hover.

Optical illusion illusions.

"A modern variation of trompe l'oeil"

Artist François Abelanet has transformed the courtyard in front of Paris' City Hall into "a new masterpiece of Land Art," on display until July 15. Who To Believe? is a giant, living anamorphosis -- a three-dimensional optical illusion that requires the viewer to stand at a specific vantage point to truly appreciate the work. [more inside]

Around and around and around we go.

Anémic Cinéma is the only film that Marcel Duchamp is credited with directing.
It's a short, just over six minutes, and was made using rotoreliefs.
You can play with some here and here.
Optical illusions present images which are "true" but inconsistent.
Inconsistency, Anemic Cinema, and the Rotoreliefs - Michael Betancourt. (Duchamp previously 1; 2;)

Escher prints in 3D LEGO versions

Andrew Lipson and Daniel Shiu build faithful, 3D versions of Escher prints using LEGOs: Relativity, Ascending and Descending, Waterfall, and Belvedere. (Only one of those four images required any photo manipulation to create its "Escher effect" -- can you tell which one, without scrolling down to see the descriptions on each page?) Other people's LEGO adventures: a playable harpsichord, the Golden Gate Bridge, and a portrait of Catwoman.

It's Also Acetaminophen-riffic.

Ready for '90s nostalgia yet? Well, throw some flannel on your Furby and get ready for that decade's most migrane-tastic fad, the autostereogram, or Magic Eye. Of course, the Web can't leave anything alone, so you can watch a moving autostereogram, play a little wall-eyed Tetris or Pong, and create your own image to delight and annoy your friends.

Trippy optical illusion

Your daily dose of perception-bending. Stare at the center of this video (wmv or flash) for a minute or two then look away from the screen at your surroundings. You'll experience an interesting and somewhat disconcerting effect. Not appropriate for anyone prone to headaches or seizures.

Transparent Street Signs

Cayetano Ferrer is a Chicago based artist whose work involves (among other styles) painting street signs with the images of the items immediately behind them, to give the illusion of transparency (depending on what angle you're viewing from). The latest campaign by Amnesty International seems inspired by his work.

It takes about a half a day to get there...

Spanish Castle Magic. Stare at the dot in the center of the image for 30 seconds, then mouseover the picture. Don't shift your glance, because until you do the picture will appear to be in color, despite the fact that it's in black & white.

The World's 1st Photograph was by Heliography

The world's first photograph was produced in France in about 1826. Joseph Nicéphore Niépce rendered a bitumen-on-pewter image of the view from his summer house in St-Loup de Varennes with an exposure time of ~8 hours. He dubbed the process, which used a camera obscura effect, heliography. Before he died in 1833 he worked for a few years with Louis Daguerre (yes, him) who incidentally invented the diorama, examples of which are among these other vintage optical toys.

Optical Illusion Sculpture

Turn Your Head is an online service that echoes the famous "two faces/chalice" optical illusion, but in the real world. You provide them with shots of your profile, and they carve a wooden sculpture of the image for only $149.95. Works best for those with uniquely pronounced features, not to mention those with $149.95 to waste on useless crap.
