That's quite a bit, since the patterns with 15 vapour > particles are quite different from one with 5. Sure, but a 10x10 isn't a sure interesting simulation. ;) > I'm not saying that this is necessarily a flaw in the solutions, I > just thought it was an interesting problem - randomly mixing > elements in a two-dimensional grid. Yes, it is interesting. James Edward Gray II
