I have the latest revision of opentouch, and when I compile opentouch to make the portVideoBlobDetection.app, I was wondering what I can do to interact with Quartz Composer over OSC. Am I right that portVideoBlobDetection.app is sending OSC messages, and it needs a listener to send the signal to quartz composer? How do I change the port settings?

I to have managed to get as far as you have stated but am yet to get the OSC listener QC to hear the OSC message transmited in Portvideoblob dection.  How about you?
