  Via my evil twin Richard Wiseman comes one of the best color optical illusions I have ever seen. The original was posted on Akiyoshi Kitaoka’s incredible optical illusion website: You see embedded spirals, right, of green, pinkish-orange, and blue? Incredibly, the green and the blue spirals are the same color.
