Motus Mentis

Some of you may recall the amazing Honda ad that was making the rounds a couple of years ago; it was a film of an elegant and complex Rube Goldberg device made entirely of car parts, and it was filmed live, with no computer animation. Well, it appears that the Japanese educational-TV program Pitagora Suichi has been collecting viewer-submitted videos of similar homemade constructions, and my colleague Jay Chang informs me that an entertaining and amusing collection of them has been made available on YouTube. Have a look here.
