University of Central Florida Interactive Systems and User Experience Lab has also released a Unity3D plugin with the new Kinect SDK.
There are also a number of openFrameworks addons for the Kinect for Windows, ofxMSKinect and ofxKinectNui.
For library Cinder, here is the Kinect SDK Block.
For Flash ActionScript users, the AIRKinect can be a good choice.
At the time of writing, I am still waiting for the Java binding and thus the Processing community.
