Hands-on: Swivl, with which your iPhone becomes your cameraman

LAS VEGAS--You move, so does your iPhone. And it's taking a video of you. Crazy, right?

This is the much-talked-about Swivl, and I got to play with it at CES.

It's simple to use. You stick your iPhone or iPod Touch in the dock, and then hang the marker around your neck and off it goes. It works with infra-red light and radio frequency.

The product is the brainchild of Brian Lamb, who a year ago ran a crowd-funding campaign on Indiegogo, a rival to Kickstarter.

He quickly raised $25,000, selling enough preorders to pay for 250 devices. The early versions got some traction on YouTube, and Lamb went on to raise $900,000.

The main audience, Lamb says, is for video bloggers. But Lamb expects lots of home users as well. How else can you take a video of yourself?

The Swivl costs $159 and Lamb is taking orders through his site. He says he'll be shipping them in the first quarter.

Check out the video interview I did with with Lamb.
