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—talked to La Información (in Spanish) and told them about how he started to make these awesome optical illusions:

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.
