VersaVersaTiles
Christopher Danielson has the most fabulous tiles (see https://talkingmathwithkids.squarespace.com/), which include his spiraling pentagons (aka pentagrins) and the versatiles. And those have the most interesting angles. The pentagrins come from cutting up a decagon into equilateral (but not regular) pentagons, and the versatiles from a dodecagon. So I was wondering about the others and made this. It turns out only 7 to 12 sides are possible with pentagons.
These flip when you click them. Solid point moves the tile, open point turns them.
