Hi folks. I'm just letting the forum know that I made a standalone app to trigger sounds based on a camera feed. Not terribly exciting news for MAXers, but it's targeted at students who don't have access to MAX.
Video Trigger is a free motion detector application tailored for media artists. Attach a camera and trigger sounds whenever occupancy is detected in six user-defined areas of the video image. You have complete control over the playback logic and the signal routing. Surround is supported.
