Rube Goldberg was a creator of ‘perpetual motion’ machines; collections of objects that create a domino like effect as each action gives the impulse for the next section of the machine.
I stumbled across this video of a lovely one by Jesse Ferguson created from natural objects.
For more machines, see this ,this or this one I made with my friend Mark Weston
absolutely fantastic *___* I would like so much to follow your workshops!...
