Big Bang Acoustics

I'm listening to Soundcheck and there's a really geeky professor on who has made audible the sounds of the universe congealing after the Big Bang. It's pretty amazing. He has a website... evidence of how geeky he really is - he seems like a guy who doesn't have time for anything but his work --- good thing, too, cuz it's amazing. His website is like an audio storybook, leading you through the formation of the universe through sound. Here's the site... (it's still not working when I make a link... but this one is worth the two seconds it takes to cut and paste!)
