Jumble Prism
Click a thumbnail to see its larger version and description.
An idea of Bram Cohen finally comes to life after 5 years.

Jumble Prism is one of the earliest jumbling puzzle ever brought into existence. Unlike the Helicopter Cube (and other jumbling puzzles) it is purely jumbling which means there are no non-jumbling turns. The turns have their center at the corners of the triangular prism.
Matt Galla made a thorough analysis of this puzzle and found:
-It has 495 essential shapes (without chiral equivalents, without symmetrical equivalents, without shapes with only one availabe turn)
-It has 967 shapes if you allow chiral equivalents.
-It has 1847 shapes if you allow shapes with only one turn.
-It has 3671 shapes if you allow shapes with only one turn and chiral equivalents.
Please follow the links for the rest of the very deep analysis.

Bram Cohen thought up this puzzle. He told Oskar about it at the beach of Surfer Paradise in Australia at the occasion of the International Puzzle Party, August 2007. Several more and less successful prototypes have been made in a collaboration between Bram and Oskar, prototyped by George Miller. Finally, this is a well-working prototype, turning and jumbling the way Bram originally envisioned it.
