Bobble-Head USB Dog

Apparently, this little bugger nods his head when he detects motion and sound and will bark if someone tries to use your computer without permission. It also notifies you of new email, alarms, and calendar events and it can even bark a number of songs like Happy Birthday.

No availability, but if you're a purveyor of crappy USB junk, they're looking for distributors.
