Hey @sarah. Just stumbled across this post.
http://forum.openframeworks.cc/t/the-stranger-installation-ofxopenniosc/11813
It sounds like it does almost everything that we need for our projects. I just tried to get it running but have had no luck yet.
At least I have managed to get some of the demos running from the ofxopenni addon. I think I will give this new find a go tomorrow.
Otherwise, I am over my head with all of this and I will resort back to Synapse until I figure out how to work with OF properly.
Cheers,
John.
