I'm Adolfo, on behalf of Fezoo, a startup from Barcelona, Spain.
We recently purchased a Structure sensor and we are happy to see that Gestoos, our gesture recognition application, works out of the box with it. If you have a Mac and Structure plugged in it, you can actually get a trial copy at our website and try to control iTunes, VLC, Keynote, YouTube or take pictures with PhotoBooth with simple gestures.
Also, I'd like to thank Occipital guys for keeping OpenNI2 alive
PS: Feedback is welcome!
