When you call your product 360. When you have a circle on you controller with lights. When every quadrant of the circle is a user.

What quadrant of this 360 circle will be the first user? The quadrant of 0-90 degrees, right?

No, not for Microsoft. Somehow it made sence to have the first player have the last quadrant (240-360 degrees) . Weird.

NI (Natural Interaction) mate is a small but powerful software that takes real-time motion capture data from a Kinect or other supported device and turns it into two industry standard protocols: OSC (Open Sound Control) and MIDI (Musical Instrument Digital Interface). Available for both Windows and Mac OSX, NI mate offers users easy installation and a powerful, yet user-friendly configuration interface. Keeping to standard protocols for output makes NI mate an extremely flexible piece of software that can be applied in a vast number of scenarios.
Download free add-ons and templates for a number of 3D and DAW (Digital Audio Workstation) software and instantly transform your Kinect into a powerful performance interface. If your favorite software is not yet supported, just make a request for it. Share your configurations, use cases and add-ons with others on the NI mate user forums (to be introduced in February 2012).

From the what is ni-mate page. Mostly: cool. Control your raytraced characters via for example Blender with your kinect from your mac or PC.

Build for a nerd con hackerspace in greece. Actually rather funny to use the kinect for that as well. For on upcoming conference I am organising, I might need this. Anyone knows where the source code is?
