There's a new motion tracking dock that should make apps like FaceTime easier to use.
Swivl works with iPhone or any smartphone that is less than 11 millimeters thick. The motorized camera stand follows a users movements, guided by an infrared marker on a wearable Bluetooth mic (which is included). It's a little pricey at $159. Here's a video showing how it works.
