Animated postcard: Miracle Cards

This card has two layers, joined in the centre by a rivet which allows the top card to be rotated on top of the bottom one. The top card is clear plastic with black lines printed on it and the bottom one is white with a heart and coloured lines on it. When the top card is rotated the changing moiré patterns create the effect that the heart is rotating. Miracle Cards, copyright BIZARR/m. schmölz. www.bizarrverlag.com.
