I’d like to see this too. It should be pretty straightforward as long as there’s some kind of serial port that can output the data (serial object to maybe an Arduino board, or a dedicated DMX unit that takes serial in). Then it’s just a matter of formatting the data right and having enough speed, which should be OK over USB.

Possibly some DMX units understand MIDI-style info and do the translation inside, which would be fine too.

DMX provides up to 512 channels, which is fine in Max with pattrstorage, table, jit.matrix, and multislider. If you can make do with 256 or less, then some other things are possible using zl (like rotate). Also there are zl-like java / javascript options that deal with more than 256 elements, well-discussed in these forums.

How about analyzing the luminance levels of a section of video and streaming those to control your lights? How about synchronizing your MIDI playback with the lights? Or analyzing the frequency spectrum of an audio file or synth wave, then controlling the lights that way? Lots of interesting options there.

There is a dmx box (www.lanbox.com) that has a max object for it,
along with a video to dmx example file

its at the bottom of the http://www.lanbox.com/downloads/downloads.html page.

also interested in this. will try it with the arduino soon and report back.
the plan right now is to use Max to analyze incoming video, identify silhouettes, and project the lights in roughly the right shapes/dimensions as the inputted person (head, torso, maybe even hands). fun!
