#411 - Creating memory game from carton caps

In #322, I used milk carton cups as a coaster. I’ve been wondering for what else I can use carton caps. As they all look identical, I decided to make a memory game from them. And it works well, because it is very easy to grab them and turn them around. The only thing I had to be careful about is that the form and colors aren’t visible when the cap is upside down.
