Remember Mario Paint from the Super NES? In Japan Nintendo advertised their creative tool with a clay animated Mario flying around on a SNES mouse.
Below is a second commercial with Yoshi flying around on a SNES mouse and conduct a musical piece with a Koopa, goomba, bob-omb and a mushroom. At the midpoint of the short ad, Nintendo flashes a bunch of complex pictures drawn with Mario Paint. Imagine drawing this with just the SNES mouse.
