Last week, we saw how Flash and Processing code can create custom VJ and visualization tools. Custom code means custom results, and all sorts of dynamic new possibilities for visuals. Jan Kremlacek writes from the Czech Republic to share his own projects. He’s been using Processing to create interactive visuals for clubs, based on everything from sound to motion detection to heartbeat inputs.
