"Chipwits consisted of a number of “environments” or rooms with different layouts and different obstacles. The object was to program the chipwit to navigate the room, zapping bugs, eating pie, and turning when necessary before his energy level ran low.
"The programming was done, in typical Macintosh fashion, by dragging tiles around into logic arrays, then saving them and running the chipwit in a room. This was an interpreted environment so if the chipwit ran into problems a few clicks and you were back in his brain futzing with his logic."
Soooo cool -- it's got that "I'm building a circuit" breadboard feel to it. I bet it'd be fun to implement as well as fun to play around with.
I love the old Mac OS Classic games, as they're mostly what I grew up on besides having a Game Boy. The retro games are also inspiring, since they had original ideas instead of relying on the latest 3D engine. Mmmm... sprites...
