This is a sketch of one of the many tea leaf storage jars (which players would have to rearrange) and its corresponding pocket cutout on the shelf. The jar is going to be large enough that players would not be able to (secretly) carry it out of the room, and it is decorated with traditional Chinese patterns. There will be sensors on the bottom of the jar and the pocket cutout, so that the system knows how many jars the players have put in the right place.
