Ahh, that reminds me of another one where one was (more or less) steering a stick man on a sled. More precisely, one would create custom slopes for him, which he would then follow automatically after hitting "Play". The goal was to prevent him from falling or crashing.

There was even a YouTube video of a guy who must have spent hours creating slopes, which the stick man would then follow to the precise melody of some classical piece of music. Truly epic.

Does anyone remember the name?
