A wandering S.C.H.T.I.C.K. found this strange coded message on a wall inside Castle Infinity. What the heck does it mean?

You're thinking, "Man, it would be great to draw on the screen to solve this puzzle, especially with a felt pen with ink that stays on the screen forever." However, forces beyond our control and out of the range of the Supersonic Security Squad may severely limit your computer time to, well, zero, and we really need you in Castle Infinity. Dry erasable markers work pretty well. Trace advises: "Print 'em out, kid."
