A very good idea. Just prior to Rubik cubes hitting the big time I got one through a small ad somewhere (back of New Scientist?), along with an explanatory booklet. The booklet was more like an academic paper, delving pretty deeply into group theory. I struggled through the booklet, learning stuff I'd have dismissed as just too difficult/dull if it hadn't been for the wonderful cube. >I think this tangle toy probably has a number of topological states that: >(a) could be identified using URIs >(b) their relationships could be described using RDF, e.g. in terms of >loop-twists or some suchlike maneouvre >(c) sequences of operations to change from one state to another might be >derived using a standard RDF tool like cwm or Euler. > >Do we have a mathematician of sufficient skill to work out the details? > >... > >Another thought I had along similar lines was one of those tile puzzles, >where you "move the hole around" to obtain some well-ordered >arrangement of >tiles.

I did see a lovely toy the other day, actually nodes & arcs. The arcs were bar magnets covered in coloured plastic, the nodes ball bearings. Unfortunately they were about ?10 for half a dozen of each. The only thing I can think of to suggest is e-SW angle grinders. (Coincidentally, there some work I need to do on some concrete ledges in our cellar). Cementic Web, anyone? Cheers, Danny.
