Your eyes see one thing, your mind believes another!
Welcome our guest writer Stefan Van den Bergh, who runs the "Planet Perplex" website. He writes: "I've been fascinated by illusions and everything like it for as long as I remember. Over the years I've made several sites about them, and built an extensive collection." We start with surreal photographs by Philippe Ramette, which turn everything upside down, gravity be damned:
Akiyoshi Kitaoka is a famous creator of moving illusions. That is, they seem to move but they actually they are entirely static:
Warning : these illusions are so strong that sensitive observers might feel sick. You will understand when you see them full-screen.
The first example is probably the most famous of them all and a favorite in poster stores: Rotating Snakes! -
When looking at this picture, you might want to check if the screen of your device is still flat. Maybe it actually IS rippling?! -
These "rotating" ladybugs are rather simple but extremely convincing. It's hard to believe this is not an animation:
The last "not-quite-moving" picture is also a classic, pretty well-known but too good to leave it out. Stare at the black dot and move your head back and forth from the screen. The wheels will start turning ...
And these objects are moving, indeed - but in a strange way
This little animation is fast becoming very popular - and no wonder: when you first look at the spinning girl, her rotation seems to be clockwise. But when you start to concentrate on her shadow, suddenly her rotation switches to counter-clockwise! It may take some time, but the moment it happens, you are going to be genuinely surprised... (first seen here)
This ferris wheel animation is similar to the one above. Look at the left side of the wheel, and it will rotate to the left. Look at the right and it will rotate there. If you play around with it, you can make it turn wherever you want. Try it!
Unique Stereo Pictures can be created using a simple animation effect. This pool animation has only two frames, but looks convincingly three-dimensional.
I don't know exactly but it would have been much, much longer. You see, the red lines are actually painted on the buildings. He just took buckets of red paint and got into town, as you will see below. This illusion only works from one exact point of view.
Another superb example of Varini's 3-D work is the Cardiff's Harbor, where the whole site became a "canvas" for Felice Varini's shapes, which could be discovered only from a specific viewpoint...
Shigeo Fukuda is another great point-of-view artist, the true "Master of Transformations". See for example his "Underground Piano". It looks like a large pile of junk from most angles, but when it is seen in a mirror at a particular angle, it resolves into an image of a piano:
Some point-of-view illusions can also happen just by accident. And when they do, the results can be hilarious... The following point-of-view illusions display the power of precise composition and object placement in photography:
For an interesting case of "cover-up" viewing-angle illusion (and a study of Medieval morals) see this page
Now you see it ...
Now a bit of magic - let's make some stuff disappear. The first illusion is a classic, but keeps baffling me every time. Stare at the black cross in the center. Within seconds, a green ball will appear. And a few seconds after that, the green ball starts eating the purple balls, until there's nothing left !
This one has no moving parts. Just look at the black cross and see the colored fluff fade away until everything is gray. See how easy your eyes are fooled ?
Speaking about elusive color... This link is simply mind-boggling. Follow the instructions to see the color appear out of black-n-white image of the castle. Click here
Adding to more well known images (see our first part), here is a variation of "shading illusion" - these two cubes are the SAME color!

For those with a lot of time on their hands, here is a great image from Mighty Optical Illusions - try to find all 82 Absolut vodka bottles in this drawing:
