Didcot power station as seen from the 8:06 train from Oxford to Paddington fed into a motion triggered OSC generator in Quartz Composer. The OSC is gobbled up by OSCulator and MIDI fed to Ableton. An arpeggiator, scale transform and some delay later the result is pleasingly reminiscent of Steve Reich.
Unfortunately the soundtrack has gotten a little out of sync with the video that generated it, not totally sure why. It is probably down to trying to get Quartz to do too much. As it is intended to be a "live" piece (if generative can be called that) I am not too worried right now.
Many thanks to Memo Akten for the inspiration and original Composer patch. More info on how I got here on my blog rick-hawkins.blogspot.com/2009/03/listen-with-your-eyes.html
