When you were young, did you ever make little animations in the corners of your notebooks?
I know I did!!!
And they were super fun to make! Every picture in a flipbook is still. It might be a drawing of a house, or a photo of a butterfly, or a picture of a dinosaur, but each image on each page is motionless on a piece of paper – it does not move at all. However, when you flip the pages quickly, the pictures really look like they’re moving. This is an illusion of course, but it’s rather amazing how much they look like moving images.
