"The original page, which sadly has since then disappered from the face of the earth, was all about this hidden "demon face" in one of Aphex Twin's tracks, #2 (the long formula) on "Windowlicker". This face was supposed to be viewable with a spectrograph program, so I decided to try it myself." Some fun - and somewhat impressive - decoding of hidden imagery on IDM cds. The Venetian Snares cats are particiuarly great.
