An experiment with real-time audio synthesis.
Click on pins to made them resonate with the radar wave, click again to disable. Use the sequencer on the right to rotate between 1-10 notes. You can save also save your composition, like this one: http://lab.hakim.se/radar/?seed=299&beats=a-maj+a-maj+e-min+d-min&nodes=44+50+64+120
Works well in Chrome and Safari but runs slowly in Firefox.
