Thaumatrope
A Victorian optical toy popularized in 1825 by physician John Ayrton Paris. A disc has one picture on each side and is spun on strings, so the two images appear to merge into one.

Spot it
- 01Two images fused
- 02Round paper disc edge
- 03Flickering ghost overlap
Why it happens
Persistence of vision holds each image on the retina for a fraction of a second, so rapid alternation makes the brain combine both pictures into a single scene.

Image-to-video prompt“Animate this image as a spinning thaumatrope disc: the picture sits on a round card hanging from two taut strings that twist and untwist. As it spins, a second simple drawing, such as a cage or a vase, flickers and fuses with the scene. Fixed camera, 4 seconds, warm parlour light, visible paper texture.”
