Steffen Sauerteig, Svend Smital and Kai Vermehr over at Eboy are cranking out some freaking fantastic art. I first ran into their work when I saw the 2010 Gamespot/Comic-Con site skin that gamespot.com had them make.  Video at Adobe: Video

I am 100% a fan of old school isometric art and these guys do some of the best I have ever seen.
