What I'm looking for is a simple body location in space to adapt visuals
with.
For more interesting effects, the movements would be interesting to play
with velocity
of particles. Actually, the camera stream seems not very usable for this
process.
I tried to get access to depth depth texture and extract pixels to
compute the difference with previous frame.
This would get some movement representation but I couldn't manage the
first step.
My last try was with (pixel-download) but the "c" pdata array stay at 0.

in the meantime, you can try some openni applications that send
skeleton 
data through osc.
synapse: http://synapsekinect.tumblr.com/
they provide mac and windows binaries, but it's written in
openframeworks, 
so it should be compilable in linux as well.

osceleton: https://github.com/Sensebloom/OSCeleton

the problem with these is that you only get skeleton data, no depth and 
video frames.

Indeed I tried with OSCeleton but got a annoying linker error.
This would be my best chance but I can't figure what is wrong.
Maybe this evoke something to you.

/usr/bin/ld: liblo-0.26-modified/src/.libs/liblo_la-server_thread.o:
undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'
/usr/bin/ld: note: 'pthread_create@@GLIBC_2.2.5' is defined in
DSO /lib/x86_64-linux-gnu/libpthread.so.0 so try adding it to the linker
command line
/lib/x86_64-linux-gnu/libpthread.so.0: could not read symbols: Invalid
operation

Thanks for the answer.

Cheers,
Ted VjBros
