I don't remember what this is called. It's based on a failry old mechanical concept that's recently been applied to new uses. See if you can guess what it is, and what the original concept was.

You can still see previous "what is it" pictures here.

If you know what this is, or if you don't but can make up a clever explanation for what it is, let me know.

I know what it is!
