Is stereoscopy (3D) in Fez's New Game++ used in any of the puzzles?

Gomez gets 3D glasses in the New Game++ intro (activated in the settings menu thereafter). Does it reveal any hidden codes, information, or new functions in the levels, or is it strictly just for aesthetics/fun like an Easter egg?

Nope—just a fun Easter egg that makes everything 3D.

Check out the telescope room. The books below the telescope seem to be a 3D picture. Just guessing, as I have not earned my glasses yet. But clearly, something is there.
