ok, if you hate HP, ignore this, but the idea is GREAT FOR LDs! It's basically a room in hogwarts where you have to imagine a door and behind it is what you really need or can visualize. The room appears differently for different people, the perfect hiding spot and anything you need is in it. I guess if you needed a room change in a LD, you could imagine the room of requirement. (5th harry potter movie if you need a visual, get it from your local library if you need to, borrow it from a friend/neighbor).

Any other ideas for using this room of requirement in LDs who know what I'm talking about?

What about the pensive?
