WTF is that thing?

Several months ago I was patrolling youtube looking for some great music videos and came across a very unique and interesting instrument. This instrument is call a Theremin. I've never seen anything like it. It has no buttons, holes, mouthpiece, strings or moving parts. It works by.... well I guess I could explain how it works but I'm sure you'll get bored. If you do actually want to know more about it, you can read about it here. en.wikipedia.org/wiki/Theremin

I was curious to see what else this thing can do and found these. Of course it's going to relate to video game music. What else would I choose? Enjoy!

EDIT - For some reason the videos aren't showing up. Don't know if it's just my connection, this site, youtube or I did something wrong. So if you can't see the videos, then just use the links. Sorry.
