Overlooks is a light switcher which combines the map of a chamber. Using this switcher, people can easily switch on/off the correct light in the room. At the same time, they could also get the configuration of the room.

CONCEPT

What would people do if they see 20 light switchers in the room? Normally, people would press each of them separately, trying again and again, and finally, they press the correct switchers. Normal solution of this problem is to put a sticker on the switcher to indicate the corresponding light. This solution, however, is not elegant and it would leave ugly mark on the wall. Therefore, we introduce this concept to handle the problem elegantly.
