Some of you might remember the Rhombicinxhttp://twistypuzzles.com/cgi-bin/puzzle.cgi?pkey=1505
which was later followed by the cleverly named "Identity Crisis":http://twistypuzzles.com/cgi-bin/puzzle.cgi?pkey=1948
Both puzzles have an dodecahedral axis system and a dodecahedral shape although we are not speaking about the same dodecahedra...
7 months ago (in Berlin) I purchased the raw matrial for the second puzzle which combines two different dodecahedra. The last image might tell you why it took me so long to build this one.
This is an extensions-only transformation!
Edge length: 36mm which equals the Rexahedron.
Weight: 407 grams which is 18 grams more comapred with the rexahedron.
Its name: Curvy Dodecahedron
