FaceCake Marketing Technologies demoed Swivel over at the CES 2012. The idea is that all you need to do is step in front of a camera and your body will show up on the screen. You wave your hands and select the clothes and accessories in Swivel's inventory to see how they would look like on your body.
You can see a video demonstration of Swivel over at the LA Times.
