There are some well-known machines that didn't make the cut -- like this proposal -- but the ones that did make it varied from simple at-home creations to elaborate works by creative professionals.
Of course, our list is topped off by one of the most-watched videos of 2010, the machine created for Ok Go's "This Too Shall Pass."
(May take a moment to load in full.)
Methodology: We ranked the most-viewed videos containing "rube goldber" in their title or in their tags and removed 3D animations -- except 1 -- as well as documentary clips and domino-based contraptions. We'll save the dominoes for another time.
