 | Shown here is a puzzle that I (and perhaps others) have conceived.   I dub it Pentultimate.  It is a dodecahedron that has been sliced six ways, each slice parallel to and midway between each pair of the twelve faces. |  
| The image on the right shows the result of one 72º face turn. I do not know whether a mechanical version could easily be built, but you can find an excellent Java version to play with at David Byrden's Puzzle Gallery. |

| New!  Noel Dillabough's excellent software: Puzzler for Windows now contains a Windows version of Pentultimate, along with 19 other magic puzzles!
