More Optical Illusions

I ran across this site with some pretty cool illusions...

First this mural on a building in France. Trippy, no? Trompe-l'oeil at its best.

I wonder if people inside can see out...

Second up! This neat trick! Stare at the middle long enough and the yellow dots disappear. Really!

Lastly, and the hardest: Stare past the center of this image, unfocus your eyes so theres 3 blurry images and genteelly scan the distant imaginary horizon until the two images merge into one 3d chair.

It's hard to do and easy to lose the illusion but its pretty awesome when you get the idea.
