Number Planet

Buy at http://www.shapeways.com/model/39383/number_planet.html Copyright (c) 2008 Prof. Igor Kriz & Dr. M. Oskar van Deventer. Number Planet is a twisty puzzle, like the Rubik's Cube, based on the Mathieu 12 (M12) group from group theory. Prof. Kriz published the concept of this puzzle in Scientific American July 2008: http://www.scientificamerican.com/article.cfm?id=puzzles-simple-groups-at-play Read the full story about the development op this puzzle at http://oskarvandeventer.nl/M12/#NumberPlanet

This puzzle was 3D-printed using nylon-powder SLS technology, which explains its price. It is the very first prototype, costing its designer and maker a lot of money to create. Please do not confuse it for a cheap mass-produced puzzle.

So... do you HAVE to invert all the tokens when you invert them?

I'm just curious.

If yes, how'd you make that work? And if no... well, then I know. I guess. XD

[OskarPuzzle]

@SwiftrunnerXXY Yes.There is a hidden mechanism that enforces the full invert.

Why haven't you prototyped the Number Star (Yes, I remember.)?

[OskarPuzzle]

@Jorbs3210 Too expensive, no sponsor ...

@OskarPuzzle Oh, okay. I see. I forgot about some of your lighter puzzles. Thanks for the advice! :D

[OskarPuzzle]

@Chyaman09 Thank you for the compliment. 3D-printing cost scales with volume/weight. So you may consider buying one of my lighter/smaller/"cheaper" models :-).
