While for someone, one Rubik's Cube is hard enough to solved, let alone solving two or three simultaneously. How about solving while juggling something?
David Calvo is something of a Rubik's Cube master. From solving two cubes simultaneously, one in each hand, to solving a cube blindfolded, he's done it all. Well, most of it. That being the case, it looks like he's started to work juggling into his repertoire, giving him the most impressively useless other skills section of any résumé in history. Of course, knowing the guy's background, it was probably harder for him to get a hang of the one-handed juggling than anything else, but it is still impossible not to be impressed. What's next? Who knows, but I am excited to find out.
Now this is what I call multitasking!
