Julian Cash is our photographer for ApacheCon. The man is a genius. He’s doing this cool thing called “painting with light” where he takes time exposures in a dark room, while playing with colored lights. The results are amazing. This and this are other favorites. I’d be glad to show you the rest of them, too. They’re more impressive in higher resolution. And I expect he’ll have the other ones he’s taking this week up on his website some time soon.
