ZDK For Unity3D
The ZDK supports both Unity native and WebPlayer builds for motion-controlled apps. The Unity package included with the ZDK Unity bindings comes with several fully functional sample scenes so you don't have to start from scratch with your game. Like all the ZDK offerings, the ZDK for Unity3D works with both Mac and PC, with OpenNI/NITE and the Microsoft Kinect SDK, and with all consumer-level 3D sensors.
