Ambiguous Objects - The Round Squares | Prof. Kokichi Sugihara
Overlapping cylinders transform into overlapping checks in the mirror.

Optical illusions have fascinated people for a very long time. Professor Kokichi Sugihara of Meiji University develops objects that appear completely different when viewed in a mirror. Viewing the real image simultaneously with the mirror image creates a fascinating optical illusion.

You will receive the object, made of white plastic, without instructions. A mirror is not included. The objects are licensed by Professor Kokichi Sugihara.

Who is Kokichi Sugihara?
Kokichi Sugihara is a Japanese mathematician and artist known for his three-dimensional optical illusions that make marbles roll uphill, pull objects to the highest point of a building's roof, and make circular pipes appear rectangular.
His illusions, which are often videos of three-dimensional objects shown from carefully chosen perspectives, won first place in the "Best Illusion of the Year" competition in 2010, 2013 and 2018 and second place in 2015 and 2016.
