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.
