pitagora suiichiEngadget reader BG suggested we have a Rube Goldberg machine contest on Engadget in the near future — not a bad idea! Remember how insanely amazing Rube Goldberg machines were to a childhood imagination? (Ever try making them with stuff around the house when you were a kid? I did, but we never had anything good enough for much more than a one or two stage machine.) Well, as proven by the mack daddy of all of them, Honda’s Cog video, Rube Goldberg  machines are still freaking awesome, and the vids on YouTube of Japanese pitagora suiichi (Pythagorean machine) are every bit as mesmerising as you’d imagine they would be were you five years old again. Just beware, the pitagora suiichi have a chirpy little jingle that plays about forty times and is rather liable to get stuck in your head for days.
