My caveat is that the multi-plane effect achieved looks fine with animation, but might look stupid with live photography. The multi-plane effect made things look layered, but the layered objects themselves still looked incredibly flat.
I think this technology is a boon to animation, but I don't think it will work as well with live films like Star Wars.
Though 99.7% animated films like the prequels should work fine!
Edited to add: The glasses were given away, there was no need to steal them. They are obviously cheap enough to include in the already-hefty theater admission.
