I might be having a false memory but do any Ausoids remember a 3D animated cartoon short from the early 2000s on ABC kids that was about math or science problems? It aired in between other shows. I think it was an alien trapped in a metal room and he had to solve whatever problem was on screen before time ran out. If he got it the door would open to show a white void, if not there was a dramatic pause as if something terrible would happen and then the punishment was always something silly like getting sprayed with foam, then he'd be let out.
