Last night while doing a patent search I came across a mechanism totally different than what my own cube looks like. It is U.S. Patent # 5826871 Oct '98 Basically, it is a standard Rubik's Cube with the central layers hidden underneath and one quadrant is fixed in place. I am wondering if there exists a web site with all the diagrams of all different puzzles from their patent pages. As you may know, patents and patent diagrams are *not* covered by copyright issues, you may photocopy them for personal viewing and even display them on a web page. I think such a web page would be nice to have; a web page of all the diagrams of the working mechanisms of all the puzzles discussed on this list. (The thing is though that soon the U.S. Patent office will be adding the diagrams to their web pages. www.uspto.gov) Anyone wish to start such a page? I have access to a patent depository. :-) -- Douglas Zander | dzander@solaria.sol.net | Shorewood, Wisconsin, USA |
