Here's another great flickr artist. He calls his photos lightpainting. Made with long exposures and a flashlight or sometimes a neon tube. Sometimes he's in them, but mostly it's shapes and designs made from light. In reading his comments, sometimes he combines as many as 8 or 9 images of 3 minute exposure each to create a finished photo. Really creative!
