How do I display video from a webcam fullscreen?

I'd like to be able to display the video that's coming in off a high-quality Logitech webcam fullscreen.

Unfortunately, the only apps that seem to be able to do this (PhotoBooth, FaceTime), flip the video so that it's useless.

Is there any 3rd-party solution out there that would solve this? I really hate to use a kludgy workaround like taking the Skype setup screen and clicking and dragging it until it's fairly large.
