I created a 3D scan of my noggin using a Kinect and the Skanect software. The results were okay, but a lot of the fine details were lost. I brought the model into ZBrush to clean it up and sculpt some of the small details back in. The process is very new to me and I couldn't get the eyes right just yet, but I am otherwise very happy with the results.
Feel free to download my head and scare people with it, or use meshmixer to put my head on strange bodies - whatever really!
