Sound of the big bang?

Not content with having the 'sound' of a solar flare (which sounds like some squirty cream) the BBC have also got the 'sound' of the big bang (it sounds a bit like a van driving past). The 'sounds' were created by John Cramer of the University of Washington using data from the WMAP probe. The sounds are actually oscillations in the early universe (within 760 thousand years of the big bang) but shifted to higher frequencies so we could hear them. He also managed to get a plug in for Mathematica. The University of Washington have a link to his article but they seem to have been overwhelmed by BBC listeners so now provide a link to another page (to catch the message you'll have to be a quick reader).
