can anyone find an earlier falling sand type game?
edit: Found this after some googling: http://cowboyprogramming.com/2007/03/05/falling-sand-game-fr...
very interesting! (includes assembly source code)
Atari ST game, in the same genre, from the Jan 1993 issue of ST Format: https://www.youtube.com/watch?v=SHZB9nIzZ64
