This one is abased on the concept by Sausage for “Sausage’s Cube”. This puzzle was designed and built with Wayne’s permission. He suggested we come up with a new name, and we settled on “Compy Cube”, naming it after a famous little dinosaur.

It’s a very easy puzzle to solve which makes it a lot of fun! I think people who are intimidated by twisty puzzles may find this one fun and rewarding to play with.

I’ll be offering a very small run of these puzzles for sale soon. They will be 3D printed. As always, the mailing list at http://www.thetwistystore.com is a great way to find out first.

The straight-cut Radiolarian is finally finished! This one has no centers which allowed me to add some nice corner and star-arm interior mechanisms (with none of the fudging used in the Cornered Radiolarian).

The prefix circo is a nod to Circogonia Icosahedra, the organism that isnpired the Radiolarian name.

I’ll also be calling it Radiolarian II.

This is a pretty minor update. But as some of you may have imagined, the Radiolarian was designed to minimize the star pieces around the corners, in hopes of keeping both the fixed face centers and the corners.

Doing this involves minimizing the star parts on the surface and in the mechanism and then fudging the rest. For folks who have imagined this mechanism, 4 star parts anchor the corner and the 5th interferes. The result works, but turning quality is only poor.
