The past couple weeks I've been playing around with audio reactive spring systems. My idea was to create a particle system held together with springs that would help visualize wave patterns and reflections in different geometric spaces. The program I ended up with this weekend has a little over 20,000 spring connections, though it's more visually interesting than educational or revealing about acoustics - fun nonetheless. I'm attaching the application here since it was too slow to really capture well with video. Also, I think this is maybe the first time I've 'shipped' an app (not sure if this counts :) ).
