What in the sorcerous hells is this? Kokichi Sugihara’s ‘Rectangles and Circles’ illusion is a mind-bending visual trip that turns squares into circles and circles into squares correct in front of your face. Different shapes are placed at a mirror and what you see in front of you is totally distinct from what you see in the mirror. It is like the mirror is really a portal to another dimension exactly where squares are circles and circles are squares. Seriously … what the hell?
