If you're looking for something cool to do with your Kinect, I suggest you use it to make 3D models of yourself and your living room.
Website Kinect@home has all the details, but basically, you take video of yourself and your home, and then send them to the site, where "robotics and computer vision researchers" who need "vast amount of images from everyday environments" will use you and your environment improve their robots' algorithms. They basically stitch together your images and create a 3D mode. You can import the 3D images into 3D editing software.
Here's the basic instructions. Get to work!
