Description: Anna Gardberg makes pentominoes out of sculpey and agate.
I discovered pentominoes in Arthur C. Clarke's book . The GIF that you see above is one of the more than 2000 ways to fit the set of twelve pentominoes into a 6 by 10 rectangle. One can also fit them into 5 by 12, 4 by 15, and 3 by 20 rectangles. There are only two 3 by 20 solutions, to the best of my knowledge.
