I got my video art installation up & running. The final will come somewhere in the near future.

I'm also going to try out other techniques discussed in this topic

For this setup I used Max/MSP/Jitter. A good friend of mine helped me build the patches. One patch trace movement over the x-axis (by color) and gives a signal to another patch, which generates an midi-signal. The midi signal is being used in VDMX by a crossfader. So I can switch between layer 1 and layer 2 by movement, to get the desired effect.
