Hidden Door Latch
I am looking for a secret "latch" to open/close a bookcase that covers a hidden door. There are some nice electromagnet types but they are expensive and need power. Any ideas on a "Chinese puzzle" type of thing where you move a couple of things and it opens? I don't want the classic horror movie things like move a book, lever or statue 'cause that's the first thing someone would try. Just fishing for ideas!
