Remember those codewheels... wow.
How about some special printing on the CD that shows up only on a red color filter? ^_^ Now that would be interesting. You'd need the real disc, because scanners and pictures would screw up the coloring.
"What symbol appears in the 3rd row, column 4?" And you'd hold the disc against the red filter, pick the right one, prompts to insert the disc...
Now THERE'S a new twist on an old idea. ^_^
