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.
