Framework: HexaPents in VPython (back to using Python 2.4) Re: http://www.4dsolutions.net/ocn/hexapent.html (recently modified). So Adrian (author of open source Packinon) tells me you need to twist it that way to make the hexagons lie flat. The Rick Bono way (dome.exe -sb), of punching out faces in a Class I icosasphere (Fig 2), gives hexagonal and pentagonal regions, but not with a flat horizon, or so goes the tale. I've taken the OFF file generated by Packinon, intermediate to the POV-Ray file used for the rendering (Fig 1), and fed it through my neighbor finder (brute force) to come up with a globalmatrix data structure, per my posts earlier this month. This data structure is used in tandem with a VPython rendering of the hexapent itself (in terms of edges -- I keep a handle on all of them to facilitate easy resizing and recoloring). The demo starts somewhere, then randomly flits about the globe, turning the current hexagon (or pentagon) red, and leaving those visited green (Fig 3). White is the default (untouched) color. You can study a random walk and see how many cycles, on average, you might need to turn the whole sphere green -- other games (I'm sure you'll think of some, if you get into it). Kirby
