Can Item Frames be nested?
Can you place an Item Frame within an Item Frame? How about an item, inside an item frame, inside an item frame? If you can do this, is there a limit?
An item frame is an item, so you can put it in an item frame. However, an item may only be placed in a frame by right-clicking a wall-mounted frame with it, so frames in your inventory are always empty. Thus, you can only place an empty item frame into an item frame.
