If there's a Kinect for Windows device under your tree, here's the development resources you'll need to start building the future...
Develop the Future with Kinect
The Kinect for Windows SDK version 1.6 and sensor can help you develop immersive applications that harness voice, movement, and gesture recognition. The latest version of the SDK, released in October 2012, gives developers more powerful sensor data tools and better ease of use while offering businesses the ability to deploy in more places.
Start by first downloading the SDK, and then the accompanying developer toolkit.
