I am trying to use the processing code from http://moullinex.tumblr.com/post/3180520798/catalina-music-video to make point clouds for a project I am working on. I tried creating a stand alone application from the source but all I get is a blank grey screen. The program runs fine in Sketch mode but I cannot record from sketch mode. Does anyone have any ideas?

I'm new to Processing so any attempts to dumb down a response will be greatly appreciated.
