Sound Arcs, revisiting
This video recording done with my cameraphone.
A nifty addition to the sketch - everything is inside a big sphere lighted with a spotlight, which gives us a very nice gradient to the background. Hack came off this processing discourse topic.
Windows application is here, Mac application is here. No sketch-in-a-browser for this one. The code is in the zip file.
Yep, and music credits - soma.fm presenting "Urchin" - not the 70's band google's throwing in its searches.
