Buy at http://www.shapeways.com/model/33171/... Copyright (c) 2009 Oskar van Deventer. Astroid Attack is a twisty puzzle like Rubik's Cube. It is based on Bram Cohen's "jumble" concept, where the geometry is no longer isometric and faces do not turn in regular steps of 360/N degrees. This puzzle has the geometry of a square anti-prism.
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.
