deviantART: Grid Game by ~Fam (game)

Here is a nifty game where you try to make a chain reaction, the larger the chain reaction, the more points you get. It is interesting that after you play for awhile that everything becomes much more ordered. Also it is interesting that the longest chain reactions occur when there is a mix of ordered and unordered cells... could be a good lead in to a project on avalanches or something.
