Those "special" serve the same purpose as the protruding octants on the 4^3 internal ball -- to anchor one of the blocks in each plane. Otherwise, one of the planes of "clips" may be offset 45 degrees (not obvious from the outside), and the other planes become unturnable. Make sure that one weird clip is in each plane before assembly. -- Wei-Hwa Huang, whuang@ugcs.caltech.edu, http://www.ugcs.caltech.edu/~whuang/ --------------------------------------------------------------------------- I hate formication.
