I've been getting acquainted with the world of DMX lighting for a while now. Recently, this materialized as a control system for the lights at the Spinni clubroom.
It's built around music analysis software from Wavesum. The DMX fixture modules, as well as the one used for the Logitech Dual Action, are available from my userpage. A big shout-out must go to kalle, who helped me in my early attempts to patch DMX, and has a load of very helpful DMX modules available - many of which are used in mine. That's one of the things I like about vvvv - effortless modularity.
