Reaktor Group Project - 'Pinball Wizard'

Glad you stumbled upon Newtonian - love that ensemble.
Just wanted to mention that it might be useful to look at terrain map by David Morris, Ball Env by Ignasi Alvarez, Orbital Osc by Cursor Miner and some of the old patches from Solar X and Programchild for collision detection. Another interesting option would be to model Mass/Springs and attach them to the nodes from something like Node-E which would be fun for event generation or Scanned synthesis if traversed at audio-rate
