Unlike last week's Lego robot, which was just okay, this robot from academic research group Advanced Algorithms for Control and Communications (AA4CC) is absolutely great at it. (To be fair to the Lego robot, it was made out of Lego blocks and it really was fine, which is saying a lot.) This robot, however, is a) very precise, and b) decorates the eggs with stroboscopic patterns that create animated zeotropes. You'll understand what that means once you watch the video.
