Flash Particles in Video

Adobe CS4 comes with a free month of learning at Lynda.com. I'm totally pumped up about learning some new stuff, and I have been using some time to pick up back on on some Flash learning. Not much to show, but I did spend a little time learning about particle systems. Todd Perkins leads a challenging and informative course on particle systems.

Here's an example file that dynamically loads particles over a video frame - the particles are generated from areas of white pixels.
