Impossible objects, like those drawn by artist M. C. Escher, don’t seem like they could exist in the real world. But Kokichi Sugihara from Meiji University in Kawasaki, Japan, is well known for building 3D versions of these structures.
Now a new video shows his latest construction: a gravity-defying roof that seems to attract and balance balls on its edge. When the house is rotated, its true form is revealed.

I love illusions. I think you’ll really love these. These are not the usual, run-of-the-mill illusions. Watch, you’ll see what i mean. Very creative stuff that must’ve taken him a very long time to setup. Enjoy!
