Erick has a trial version of Spore for the iPhone.  Neat game.  You “evolve” by eating smaller organisms and work your way up developing better defenses against predatory organisms.  The creatures are fun to develop, but so far I’ve only been able to play around in the primordial goo since we don’t have a full version.  

Oh, the things I would do if I were a single-celled amoeba.
