I get it: For years, folks have been doing all sorts of crazy-amazing Rubik's cube solves. So it's not like this sort of thing hasn't ever been done before.
And yet it's the first-person perspective here that smokes every other watch-me-solve-this-brain-teaser homevideo ever made. Ever. Why? Because upping a FPV video of this sort to YouTube suddenly allows increasingly-clumsy chumps like myself, competent in neither juggling nor Rubik's flawlessness, to be both competent jugglers and masters of the legendary 3D-combination puzzle. This is what the dawn of the armchair-everything looks like.
While we're at it, let's talk right quick about the other people in this video, particularly about how seemingly unphased they are by someone--presumably a friend?--juggling and brain-teasering with a GoPro strapped to his head. Unreal. Guess they'd rather just relive it later on the internets rather than actually give dude his moment of glory in real life? Because that's just so awkward.
