There are days I think I'm working one desk away from Batman, and then there are days like today that leave no room to doubt.
If you shine a blue light on a color photocopy and look at it under a magnefying glass, you'll see a repeating pattern of black dots that
encode printer information. They're actually printed in yellow pixels, the blue light turns them black.
Guess who pointed this out because he has a use for this information?
