Found over at Easy Bake Coven: a link to another interesting art site, this time one Trevor Brown. In his links list were a couple of other noteworthy art sites: Camille Rose Garcia, John John Jesse and Alex Gross.
I should say at this point that Brown and Jesse's sites are not safe for work. Of course, I don't have to worry about that right now. Garcia and Gross' sites are not so X rated, but people will probably look at you funny if you check them out at your desk so I wouldn't advise that either.
Chris, you in particular should take a look at these sites, you'll love 'em, especially Jesse's.
