I thought of something to help both waiters and patrons in a restaurant. While restaurants want to have a dim, ambient mood, patrons often need help in reading the menu. The opening and closing of a menu would increase and decrease the luminosity of the closest light, helping the patron read the menu easier. It would also help the waiter to know when the patron is ready to order, especially in settings where it may be difficult to see the menu placed on the table.
