The first Kinect app popped up in the Mac App Store, called “Kinect 3D Viewer” for Mac OS X 10.6 or later allows you to plug your USB Kinect into your computer and view a 3D visualization of the depth data.
You can also map RGB values onto the depth image. Additionally, you can zoom and rotate the visualization.
Kinect Viewer is based on the hard work of the people from OpenKinect.
