This Awesome Optical Illusion Will Twist Your Brain Into Knots

Kokichi Sugihara loves to screw up human perception. He is the master of 3D optical illusions, designing solid three-dimensional models that do impossible things. This house is his latest creation, presented a few days ago at the European Conference on Visual Perception in Sardinia, Italy.

Sugihara—a mathematics researcher and professor at Meiji University in Kawasaki, Japan—got interested into 3D optical illusions while creating a machine to turn 2D line drawings into 3D objects:

I'm a mathematician. One of the things I've been working on is a computer that can interpret bi-dimensional line drawings as solid tridimensional objects. To test this machine I scanned drawings of impossible objects, expecting that the software would say that they were impossible to make. However, sometimes the program turned these objects into real objects, and that's how I discovered that some impossible objects are not really impossible—they can actually be built as solids in three-dimensional space. It was that experience that got me into optical illusions, particularly those of 3D objects in motion.

This is very impressive. The only thing that gives this away is the way the top of the house is lit. The light source is above and to the right of the object so the side of the house that starts on the right side should be brighter than on the left. I am not trying to take away from this amazing piece, just an observation.
