Kickass light painting

Don't know how I've never heard of light painting before this week. I'm not a photography nerd in any sense, so I still don't fully understand the concept. Something to do with exposure, nighttime, lens magnification, film saturation, visual qualitantification....now I'm just making up words. But it doesn't even matter. I know kickass art, and this relatively new art form is amazing and kind of wondrous.

One artist I'm really loving is Trevor Williams. Check out his work here and some of his pieces below.
