Illusion of the Week: The world
“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.
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.
