Erik Johansson takes pictures and then digitally manipulates them. So do lots of other people, but not many get such interesting results. If I had to guess, I don’t think he’s from outer space, but the universe next door wouldn’t surprise me. I thought the link to this artist came from Six Revisions, but now I can’t find it to confirm. That doesn’t mean you shouldn’t visit that site; lots of great info about building your own piece of the web to be found there.
