Many have attempted, some have succeeded (see: the Mythbusters crew or the band Ok Go). I have no idea how many have, but I think we can agree on the fact that constructing a Rube Goldberg machine in the first place should be applauded. Each one differs in size, shape, and difficulty, reflecting the cartoonist and inventor's original concept he first drew in 1914: "the machines are a symbol of man's capacity for exerting maximum effort to achieve minimal results."
The latest one I've come across, completed b 2D Photography, a professional photography collective in Toronto, has just blown me away. I'd rather not waste any more time setting up this video. But I will say this particular Rube Goldberg machine — featuring lenses, light kits, and memory cards galore — looks pretty expensive...
My favorite part of this project is the fact that the creator explains his process. As a matter of fact, David Dvir, the lead photographer at 2D Photography, shares his secrets in this behind the scenes video:
Perhaps my fascination with Rube Goldberg machines comes from the fact that there's no limit to one's imagination. To my knowledge, I don't think there's a rule that states you need dominoes to create the initial domino line to start the whole thing. Or that the contraption pours you a glass of milk halfway through. We get to explore a person's thought process through a zany piece of art.
