Position of all the objects are based on Blob detection from built-in webcam. Size, color, and opacity are determined by the input audio of built-in mic.  Blob Detection and Sonia Helper come together to make this processing sketch. An extension of the prior blob detection with Apes on Tapes. /*--------------------------------------------------- I feel as though I’m getting close to something interesting, it's not quite there yet. The connection between the audio and visual should be more apparent, imo. I've posted on my blog some other thoughts that I think would make a worthwhile app...ie extending this processing sketch to a bonafide app that can be used with a midi controller. ---------------------------------------------------*/
