Paint with light using Glow Doodle

Glow Doodle is a quirky drawing app that lets you draw with light, and you can try out if you've got a webcam. If you've ever taken a photograph of something moving and seen the streak effect, you'll get how it works. Open up the app, and get some kind of light source, like a cellphone, and move it around in the air. It will leave a trail, and you'll have a light drawing.

The controls for Glow Doodle are pretty simple: click to clear, s to save, and space to upload to the online collection of glowdoodles. Experiment with different objects to see what kind of results you get. The reflection from my glasses worked pretty well, and I imagine a shiny watch face would be pretty good, too. I didn't have a laser pointer on hand - I know, I'm such a bad geek - but I'd like to try different light colors and see how those work.
