Does anyone know of a good plotter for this guy? If he's got CADD software he may as well find one. Did the HP PaintJet or whatever they were called ever work on a Mac with adapters?

Also, you might want to check out Cliff Johnson's site and grab his games. He wrote Fool's Errand, 3 in Three, and At the Carnival and offers them free of charge from his website--all three are excellent puzzle games.
