Another optical illuson

Motion in Non-Motion

Here you find a series of slits roving across an illustration, thus allowing only small bits of information at a time. Our brain then fills in the gaps of different stages and recreates the experience of viewing fluid movement. If you're feeling dumb and disappointed in the power of the human brain, don't—as you can see, the cat in this video was also fooled.

Seems to be a variation of a Zoetrope (https://en.wikipedia.org/wiki/Zoetrope). They were popular in the mid 1800s. Video of one in action - https://www.youtube.com/watch?v=SBg6dAE3mI0

You are correct.  I hadn't thought of that until you mentioned it. Thanks!
