Using the standalone (AIR-based) version of Fnk with a webcam to create circles that match the camera color at random positions, then using the perceived camera activity level to control the maximum circle sizes.
Framerate is low due to the video capture process. The actual execution runs at around 20fps for a 320x240 output with 100 new circles every frame. It's still lacking some optimization though.
