I didn't know who he was - looks pretty awesome though:
"Jonathan Coulton is the Contributing Troubadour for Popular Science magazine and the musical director for John Hodgman’s Little Gray Book Lectures. His songs about vengeful nerds, ennui-afflicted clowns, self-loathing giant squids, and devotees of a certain Swedish prefab furniture store are insanely clever without ever being too clever for their own good."
