The other day I came across a
very cool video (called "Lightning Doodle Project" methinks) done with what I assume was stop action, long-exposure photography, and a variety of small light sources. The participants draw out animations and figures with these lights, much like the
sparkler photos I blogged about in the past. Take a minute to watch the video. Here's a link to
the site it comes from for posterity (it's in Japanese).
