iRobot (who makes the roomba) is coming out with a new robot you can control over the internet. if i ever get time to finish building my robot i want to mod it to do something similar. i feel bad for my poor robot, thanks to my lack of time and "ooh i should add this feature too" mentality he'll end up like edward scissorshands. on the plus side, he'll be loved by millions of goth and emo girls around the world.
