This reminded me of a toy I had as a kid: the Tomy Tutor Play Computer. The screen was a lenticular lens over a paper scroll, and pressing the space bar caused the lens to move vertically.

Here is a video made by someone selling one: https://www.youtube.com/watch?v=TAghB2-Ks5I

I bet many of the people here can guess the fate of it and many of my other toys.
