Although most WebCams work fine on Macs they don't list support for Macs on the box. Not so with Gear Head. It took about 15 minutes to download Skype, open an account, configure a few parameters, and connect with my daughter and grandson in Switzerland.

This is a 1.3 megapixel camera, has face tracking, zooming, autofocus, and a resolution of 1280 x 1024 for both video and pictures.

There are entry-level WebCams for a bit less, but this WebCam at a list price of $50 is well worth it for the added features.
