FaceTime is a cool idea, but holding the phone still to make a perfect video conference can be an issue. Likewise, shooting video with the iPhone is all well and good--unless you want to be in the picture--then it's not so easy. Swivl may be the answer, at least if you're really serious about your FaceTime experience.
There are two pieces to the Swivl system. First, there's a motorized cradle for your iPhone that, as the name suggests, swivels as you move. Along with rotating, Swivl can also pan up and down as it tracks a fob that you or your subject wears. In normal mode, it moves at a constant speed that's comfortable for the viewer; in sport mode, it tracks the subject--but you'll get some blur in the background. The Swivl system will run $159 when released later this year.
