Webcam that mounts at USB port

Way back when, I wrote this on Warner Crocker's blog:
[However, I would love a camera that mounts at the USB port so it acts practically like an integrated component while still being removable.]
Well, I found one at Radio Shack today. Pretty cheap but it mounts where it plugs in and faces away from the screen. Still need to set it up but I am very excited to get it going.
