sound bird is an audio reactive painting being living on the screen. Sounds from the external world boost its energy and its colorful trails creates abstract sound mapping of the environment

User Scenario
The sound bird has a constant (but not regular) motion across the screen, flying through the huge horizontal space of the pixel wall and creating painterly maps of the environment sounds.
If no sound is present (i.e. no human presence) the bird will fly on his own, leaving no trails and in a smallish and a less protagonist size; the presence/interaction will turn the bird bigger (stretching its wings) and will leave a mesh of color in their path, representative of the sound level in the ambient.

Implementation
code running on Processing/Java using Daniel Shiffman's MostPixelsEver Library
