Spinning Animations

Children can interact with the toy by spinning the top, and watching the animations produced by the series of images on the side. They can also change the animation by sliding out the strip of paper that the images are printed on, and exchanging it for a strip of other images.
The top gives children a basic understanding of inertia, and, to an extent, centrifugal forces. It also teaches about speed, and the effects that it can have upon viewed objects and images.
The toy would be reasonably cheap to produce, as it has few components, and a very basic construction. As an object that is not taken apart by the child, except with the removal of a paper strip, it would be very durable in the long run, as well as safe, as there are no small, removable pieces forming the top.
