This is another demo of the visuals I'm building for the Roots bricktable (built by Jordan and Owen) to be launched at the Minitek festival in New York this weekend - The earlier demo was at vimeo.com/1569676.

To summarize quickly - using your fingers (on a multitouch table) you can draw and create 'roots'. These wander around the table randomly triggering and controlling audio/samples. Using fiducial markers you can create and modify force fields to alter the paths of the roots, and also play with some knobs to alter more parameters - and ultimately control the evolution of the generative music.
