Electro-Mechanical Thaumatrope

The Electro-Mechanical Thaumatrope is an updated version of the Victorian toy.

Two parts of an image or message are printed on either of a piece of card.

When the device is activated the card spins and combines both parts together.

For example, if a bird and a cage are on either side of the spinning card, the free bird will now appear to be trapped in the cage.
