Inside an M.C. Escher world

3D modeling software allows us to enter one of M. C. Escher's disorienting worlds.

Lego illusions

Mighty Optical Illusions is an always interesting site to visit. Some of my favorite illusions at their site are there Lego illusions. They have a page which links to samples of optical illusions made out of Lego blocks that they have gathered.

However, while the illusions are fascinating, I can't help but wonder how many Dads swipe their kids Legos on Christmas morning so they can play M. C. Escher with them?
