FOUR HANDS by Victor
Victor's Four Hands tessellation has rotational symmetry. See how the pizza shape is at the center of two pairs of (sleeping? pizza-eating?) figures in pointy hat pajamas. Each purple figure is a repetition of one 180° away from it around the pizza, and except for its colored clothes is identical to the figures 90° and 270° away from it.
I'm quite pleased that Victor obviously took the time to tweak this shape. Notice how the little square feet are offset, and one foot swings back to fill in the mouth of the figure behind it.
