I've seen these and thought about unsung something similar. But I was
hoping to not have to build the little parts myself. Seems like a pain
trying to get reliable behavior out of hand made springs. And I'd need at
least a dozen and a couple hundred is possible.

BTW.. My cat steals pens and pencils.
