Ani-what? The kids pulled this off the shelf on this morning and we played with it for a LONG time. The principal is similar to the flip-book animations that we would make as kids. On a circular piece of paper, there are sequential images that differ only slightly from the one before such that the image appears to move when the wheel is spun rapidly. The image is viewed through a square window that is aimed at the image’s reflection in the mirrored piece above.
Sadie then made her own- an animation of a bouncing ball.
