It's Ratfist! (story started here, 17 updates ago) The webcomics world is semi-agog about this new daily entry by previous-master-of-other-media Doug TenNapel. Did somebody say "who?"? Just the well-warped mind behind landmark video games Earthworm Jim and The Neverhood, and unjustly forgotten toons Project GeeKeR and Catscratch, among other stuff.
Doug TenNapel reviews "The God Who Wasn't There" in three parts: [1,2,3]. (Religion not your thing? He also does comics. And video games.)
