I recently completed a mechanical bottlestopper - the kind that has parts that move when one pulls the string. I don't have a photo of it, but I did make a short movie of it working. It's roughly 180KB in size, so it shouldn't take too long to download. It's a .MOV file, so you'll need Quicktime or some other video player that can run .MOV files, or the Quicktime plug-ins for your browser.

For Ron:
It's a bald, round-headed character about 3 inches tall (above the cork) He's holding a mug of beer in his right hand, and his left hand is in front of him, palm up, as if he's been gesturing while talking. When you pull the string, the head tilts backward about 45 degrees, and the right arm moves about 90 degrees, lifting the beer to his mouth. When you let go of the string, the hand with the beer mug comes back down, and the head tilts slightly forward again. It seemed a lot more fun than the standard violin player...
