Look, I'm already a huge fan of geek god indie rocker Jonathan Coulton. Combine his pop sensibility with the same kind of cheeky font-nerd animation that made Cee-Lo's naughty language song (NSFW, yo!) such a viral video hit earlier this year, and you've got the kind of bait that pulls me right in.
Animation by Jarrett Heather, obvious candidate for "JoCo superfan of 2010"
