This does not make the puzzle easier. Apart from the jewel i also have a taiwanese and a polish made octahedreon (with vertex pieces). A third version exists, made by Uwe Meffert, but quite rare. The turning quality of the jewel is very close to that of the polish made octahedron, so i believe that is where the jewel originates (Correct me if i'm wrong, Christoph!) The disassembled polish octahedron has a mechanism very close to that of the Pyraminx puzzle, also by Uwe Meffert. It is not a cube mechanism. >The Christoph's Magic Jewel is a disguised Rubik's cube (cf. Metamagical >Themas by Douglas R. Hofstadter p.339 : Stan Isaacs's coloring scheme) >but what about the internal mechanism? Is it simply a Rubik's cube with >only edge and centre cubes or is the mechanism different from the >classic cube. >I haven't managed to disassemble the Magic Jewel yet. > >Geoffroy.VanLerberghe@ping.be ____________________________________ Philip K recording and performing artist Vendersgade 15, 3th DK - 1363 Copenhagen K Phone: +45 33932787 Mobile: +45 21706731 E-mail: philipknudsen@hotmail.com E-mail: skouknudsen@get2net.dk E-mail: skouknudsen@email.dk E-mail: 4521706731@sms.tdm.dk (leave subject blank!)
