How It Is Used
The disc is held facing a mirror and spun, and the viewer looks through the slots at the reflection. Because each image is seen only briefly before the next one, the eye merges them into motion. Changing the spinning speed changes the effect, which makes it a simple way to discuss optical illusion and animation.
