Holy shit, I remember playing something very similar to this for hours on end in the early 90s as a kid; it might have even been an early version of the powder toy (another user mentioned it), not entirely sure, but regardless this thread is making me go back down memory lane and now I'd love to get into the insides of a game like this one and understand how it works!
