do you know
bittbox ? probably yes but just in case i thought i'd mention it. i LOVE that guy ; he posts all kinds of amazing ultra-high res textures you can download for free, and makes crazy photoshop and illustrator brushes and tutorials as well. i have learned a lot just wandering around his site and gotten some unbelievable ressources too. everybody should have his site bookmarked. oh, and he makes fonts too.
seriously, the guy is awesome.
