One more experiment, Colored Webcam

The BitmapData class is very cool. In this experiment the was used threshold method to accomplish the coloring of the image received of the webcam.

In case you have a webcam, below the video I put the file for you to see the experiment working.

The code of the application it's the end of the page, the code is commented on.
