Hand with Reflective Globe by M.C. Escher T-Shirt

A man holding a sphere that contains the man holding the sphere. Escher didn't miss. This is "Hand with Reflecting Sphere"... 1935, pencil and ink, the artist staring back at himself in a mirrored ball while somehow also being the hand holding it. It's recursive, it's impossible, and it's been living rent-free in philosophy students' heads for ninety years. The whole world in one hand. Including the hand. For everyone who has ever thought too hard about consciousness and kept going anyway.
