This is a sample from the K4W community. Josh Blake, K4W MVP, built an application that allows you to create a 3D model of your head using Kinect for Windows. The model can be exported and even replicated using a 3D printer. Send one to your grandma!
This video provides a quick walkthrough of the important parts of the source code. Check out part one which shows how the application works and talks about the key features.
