Flash Webcam Shape Detection

• Summary:
  Experiment in using the webcam as an input device. Relied heavily on the BitmapData class (including the threshold method). Possible applications include games, assistive interfaces and probably a lot more that I can't think of right now. Please feel free to inspect, modify and rip apart (note that the Collision Detection class was created by Grant Skinner).
• Note: Requires Flash Player 8 + webcam access
