What happens when OK Go are left to their own devices?

You'd have thought the creative brains behind OK Go's ever-innovative music videos would have run out of 'how/why did they do that' concepts, but, as the promo for A Stone Only Rolls Downhill goes to show, they aren't done painstakingly torturing themselves for our pleasure yet.

Co-directed through Park Pictures by Chris Buongiorno and frontman Damian Kulash, the music video is an aesthetically pleasing mosaic of iPhone-captured imagery that, when displayed on a neat grid of devices, makes for a kaleidoscope of ideas. So far, so easy to augment with VFX, yeah?

Well, no. Don't forget that this is OK Go we're talking about - the band that taught a pack of well-trained dogs to dance for their dinner (well treats), an constructed the Rube Goldberg machine that even its namesake would find excessive - so 'faking it' isn't a possibility.
