I'm trying to make a demo of a site for a client and I need a couple of sounds.
I have a button that when you click it a window zips onto the screen to display text. I need sort of a mechanical movement sound thats not too cartoonish, because the people seeing this will be (hopefully rich) business men/women/people/humans.

Also, since this is a demo for a commercial project I'd need sounds that can be used commercially.
