Imagine What You Could Do with This! CamSpace

This free software is currently in closed beta (that means you can't have it yet) from Cam Space.  Open beta is coming and you can sign up to be notified.  It works most web cams. There site includes links to a wiki, a blog, FAQ, and a number of featured applications.

Until it comes out of beta you can play around with Eye Toy.

Thanks to Barrie from One Switch for the link.
