Windows/Mac: Glow Doodle turns your webcam into an extended exposure camera, perfect for creating hand-drawn light streak art.
We've previously showed you how to use extended exposures to photograph light trails left behind by moving objects, including stars. While your web cam is nowhere near the level of sophistication you'd need for capturing star trails, thanks to the simple app Glow Doodle, you can use it capture images created with bright lights, like LEDs. The red spiral shown above was created using a small red keychain LED flashlight.
Glow Doodle works best in a darkened room, although the galleries at the link below show off ways people have used Glow Doodle under regular lighting conditions for cools effects. If you make a doodle you're proud of, make sure to share a link in the comments below. Glow Doodle is freeware and available for Windows and Mac.
