If you missed the announcement, RadioPopper is holding a 'video' contest. RadioPopper makes some super fast wireless flash triggers, and some that maintain communication between the camera & flash without line of sight requirements. With that communication they are one of the rare triggers to support High Speed Sync wirelessly. Don't worry, the contest is not a difficult one where you need to show off award winning Photography skills. Just 30 seconds of showing or explaining your best photography lighting tips. They mention you can do this right from your basic webcam if needed. Since I have several RadioPopper PX's myself, I think i'll have to join in on this one.
