Mental_floss' step-by-step guide to destroying civilization with nanotechnology

Ransom Riggs says

I just finished a new short film project [for mental_floss]. As far as I know, it's (one of) the only short films ever made with mocap technology (the actor wears a neoprene suit covered in reflective dots ... my animators learned from robert zemeckis himself) and almost certainly the only short film to ever dramatize the nightmarish "gray goo" scenario, in which, Sorcerer's-Apprentice-like, a hapless would-be evil genius unleashes a plague of nanorobots which devour the earth. It's on YouTube -- in HD.
