Cool puzzle (and making of) over @ Puzzleforge, thanks Erin!

In early 2007, I made a pencil sketch of a deep cut vertex turning icosahedron puzzle. I later realized this ground had been covered by others before in dodecahedron form, including Christopher Pelley, who coined the name “Pentultimate”.

The first Pentultimate was completed on March 19th at around 8 PM.

Here’s a little back story on how this puzzle was created.
