The thaumatrope is an early motion device you spin. While you spin the thaumatrope your brain retains what it sees on one side when it sees the other side - so your brain thinks it is seeing both sides. Try one yourself. If you would like to learn more about making or the history of the thaumatrope go to VidKids.
The following pictures will lead you to a room eight artist's still life of a thaumatrope in motion. You may return to this page, go backward or forward through the thaumatrope slide festival or return to the Hoffer entrance.
