I wasn't aware this was a challenge -- I was just trying to help bigballa (my mistake on spelling his name earlier....). But if we want to have some kind of simple model topic put together -- just to get our creative juices flowing, I think that's very cool. What do you all say we do a quick and dirty model of, say, a cigarette lighter? First thing that popped into my mind. (And I don't smoke, mind you....)
