Speed painting

So I thought I might try out a new technique of light painting. Before I would always use flashlights to paint someone standing perfectly still, but now I've found a better method. See, my original idea for using flashlight to paint people was only came about because I didn't have an external flash. But then I realized, I had an external flash all along: a digital camera! So I had a friend point a regular little digital camera at me and take a photo with flash. That way, my entire body was exposed in an instant. I can't believe I didn't think of this sooner!
