At PDC09, Silverlight 4 Beta was released and the availability of, one of the most requested features “Web Cam Support”. Wanting to have fun with new feature, “I thought of a fun sample to create – smashing bugs with motion detection. First step was to get bugs to crawl across the screen. Next I added WebCam with frame diff calculation, which was intensive so took advantage of multiple thread support. And finally I added a little Mantis Boy avatar to visualize smashing of the bugs,” Adam Kinney.
