heh,
Yeah, that's Phil.
I prefer Narbonic for my mad-science fix, but Girl Genius is nice.
Phil's got alot of stuff, in alot of places; he's a major player in the comics industry, but very good at seeming small and behind the scenes so that many people don't realize how far his background extends.
To anyone that hasn't read it, I'd highly suggest it, and if you are an old-school AD&D gamer, his "What's New?" comics are also good.
