You know, with all these people begging for hints for puzzle #12, perhaps it's time to consider a different approach to puzzle #12.
It should not be included in the puzzles screen at all, if it is, indeed, just an easter egg. Or, if it is to remain as a puzzle, the solution needs to be a little more obvious or maybe there should be major hints in the game.
As far as I can tell, not a single person has found and solved puzzle 12 without someone giving them a big hint or specifically telling them how to solve it.
