"The world is but an illusion" -- Buddha

Wednesday is Illusion Day. Every Wednesday, we feature a contemporary illusion, or a variation on a classic illusion.

This week's pick is a wonderful example of anamorphic art, by French artist Franois Ablanet.

Anamorphic illusions only work from a particular vantage point. Check out our Scientific American Mind slide show on impossible sculptures, for 3D renditions of impossible figures and other illusions that depend on a specific viewing angle.
