http://AncientOptics.com Thaumatrope (Trompe-L'Oeil) optical toy cards demo video. A thaumatrope is a small card, held on opposite ends by pieces of string. An image is drawn on each side of the card, and is selected in such a way that when the card is spun, the two images appear to become superimposed.
Like you, I am a fan of this type of thing! Hard to video well though because of frame rate! Just shows Victorian Tech can beat 21st Century Tech!!
