The Pyraminx Crystal (also called a Chrysanthemum puzzle) is a dodecahedral puzzle similar to the Rubik's Cube and the Megaminx. It is manufactured by Uwe Mèffert and has been sold in his puzzle shop since 2008. The puzzle was originally called the Brilic, and was first made in 2006 by Aleh Hladzilin, a member of the Twisty Puzzles Forum. It is not to be confused with the Pyraminx, which is also invented and sold by Meffert. (Wikipedia).
