Halftone Effect with Flash

I am going to keep on posting my explorations with BitmapData until someone stops me.

My latest iteration turns the input from a webcam (or video) into a haltone effect (an idea given to me by Brandon Breaux). The squares analyze the intesity of the color they are over. If they are over a dark color they will get smaller, and if they are over a light color they will get bigger. This naturally causes a halftone effect.
