The Three Sea Shells

OK, I'm sure a lot of you have watched the movie Demolition Man and wondered how the concept of the three seashells works? I know I have, and I've even read the book (I'm not sure which was based on which), but no mention as to how it actually functions...any insights??

Hahahahahaha! The second I read the title to this thread, I got, and was amused by, the reference. Hehe - a pretty funny line in the movie: <laughter> "He doesn't know how to use the three seashells...hehehe."

I've no idea how they work...I think the whole idea is to get us thinking about it.
