If you place an activation block (the one that dissapears when you hook it up to wires), then a chest on top of it and connect the activation block to a lever using wires, then make the activation block disappear, when you hit the chest (there must be an object in the chest) it will make more and more chests spawn.
Become a ghost

Duplication Glitch (Multiplayer)
You can duplicate items in multiplayer, if you have a friend with Xbox Live. Join a friend's game and place the items you wish to duplicate in a chest. Now quit out to the dashboard without saving. Restart the game and return to your friend's world. Retrieve the items from the chest and you'll find that you now have an extra set. Save your game and return to the main menu, then repeat the process as often as you like from there.
