well, there *may* in fact be acid in your water cooler at work, but Ive 
also noticed a slight moire'-like pattern on the top side of the Ae CD.  
an oblique lighting angle makes it more visible, but theres definitely a 
slight surface difference.  I wonder if the also blank ABB3 cd  
demonstrates this strange property as well, which may just be a strange 
illusion created by the digital information refracted somehow thru the 
plastic.

any optics experts care to explain this?
