Building A Wooden Jacob's Ladder, And More

You've probably seen this toy Jacob's Ladder
before. I'm wondering if there are any other illusions that use the same principle, and whether they can be easily recreated by crafty amatuers.

I bring this up because I've seen some card tricks and other magic schtick that appeared to use the multiple hinge concept, and I'd like to make some of these objects with my son. Googling didn't help; if this illusion has a name beyond "Jacob's Ladder" (which gets a ton of hits based on the religious meanings and the cool electric thingamajob
), I'd really like to know how to search it out.
I know that the Rubik's Cube uses double hinges. Where can I find plans for toys or tricks that work on this principle?
