I was gonna post the other link also. I figured the article had some decent inof though. Thanks for posting it.
I can't remember which one it was, but a movie had a similar sound effect. I think it was either 2010 or Event Horizon. (BTW, if you have not seen Event Horizon, do so. Do it. Do it, now.) I remember this eerie ass sound kept playing. It was similar... You know what? It might have been the SETI signal in the movie Independence Day! I'll see if I can find it!
Ok, so, after lots of searching, it seems that I will not be able to even listen to the signal. You see, it belongs to Sony and is not available in this country...
Maybe one of our European friends can do a quick search for it? Just look for "independence day SETI signal".
