There are exactly 1000 white seeds if you care to count. This puzzle has the interesting aspect of having the sunflower lock with the su...

Inelegant So-Ma designed by Haym Hirsh, produced by Brian Menold (WoodWonders)From the description at WoodWonders: "Haym is at it again! Not only did he come up with another soma variation, he made it a second soma version in the Inelegant Series! As usual, these are quite challenging. The altered Soma pieces assemble into a cube . . . one way! They have some assorted holes in the sides created by the irregular pieces. Let me also add that Haym puts a lot of thought into the name of his designs!...
