articulated arm for iSight?

[renault4]

I was just watching "CSI Maimi" and I spotted an iSight attached to an articulated arm (similar to what one would find on a functional desk lamp); obviously it could be a prop made up for the show, but I am curious as to whether this is a real product?

I have a 30in cinema display and I could imagine using this to position the iSight in the "center" of the screen.

cheers,
