A vj and Dj program by interim_descriptor
original release statement from 2009: "For a decade, I've been working on a DJ + VJ program called "dvj". In short, it gives the user a pair of video-linked turntables: Scratching with a MIDI controller scratches both the audio and video. This is the only program I use at my shows, and I'm quite happy with it."

dvj supports projection mapping.
Current status: Last update on Googlecode repo was 2 years ago, to support OSX 10.9.
As interim_descriptor abandoned the linux version ("Linux is dependency hell") and concentrated on osx instead, there are some platform-specific parts of code in the sources, namely mach, syphon and itunes integration, so building on linux is not straightforward, and does not succeed so far.
I will try to lay out the process of compiling for both platforms as thoroughly as possible, and also provide binaries if possible.
