Donut

Tap it to break it apart and put it back together.

A frosted donut with sprinkles, built by the computer from a simple ring shape. To a mathematician, a ring like this is a torus. In topology, the math of shapes that can stretch but not tear, a donut and a coffee mug count as the same shape, because each has exactly one hole.

Tap it and it snaps into chunks that fly apart and tumble, showing the dough inside, while the sprinkles spray off. Then it all flies back together. The Make tab builds shapes like this from a shape, a palette and a seed.
