Girl on Scooter wasn't technically a game, it was more of an art piece. I wanted to create an application that you could just leave running and it would be always changing. Dynamically created worlds would be constructed in front of the scooter girl just out of camera view, so the scene would always be different. The world is actually a giant table which the scooter and camera slowly rotate around, much in the way the early Fleischer cartoons sometimes did. I actually turned up the speed on the scooter and left it on for several days, and I'm proud to say it didn't crash once. Programatically or just by hitting a large rock.
