Good Omens, Full of the awesome

I was rather sad to discover the Good Omens comic pages, in the above link, by Studio Foglio (publishers of the Steam punk comic, Girl Genius) are just fan art, but ya'll should check them out. They're on sale on e-bay right now for a large pile of money, but all the profits are going to alzheimer's research in honor of Terry Pratchett.
Maybe if they make enough the comic will actually get made.
