It looks like a Psi, but it seems to be more closely related to a pitchfork. :) See Seth Rogers' profile. Looks spooky to me and he's with a shady group called "CHAOS", an "evangelical" group operating behind the scenes. (Oh, and Halloween is just around the corner. Boo!)
In all seriousness, does anyone want to explain the choice of Psi?
Update 1: This page has a bit more background on the pitchfork brigade.
