Here is a before and after photo of the new Nine Inch Nails - Year Zero CD. Apparently after playing the cd the black goes away and reveals some thing below, a hidden message? We don’t know but thought It was a pretty neat gimmick.

Here is some more information I found on the Year Zero Wiki about this CD.

“Year Zero features a thermo-chrome heat-sensitive CD face. Appearing mostly black (except for the title), when heated the disc turns mostly white, hiding the title and revealing lines, blocks, the copyright notice and a series of zeros and ones. The binary sequence translates into “exterminal.net“, leading to a website sharing the same URL.”

If you visit the Exterminal site, click the menu item and then Inmate - exhibit A, which then will play the track “Capital G” off of the new Year Zero cd (.wav file), or you can click here for a direct link to the song.
