Metaphys designed a very interesting wall-mounted power outlet. As you can see on the picture, this outlet as some grooves all around it. Since Japanese plugs are flat, you can plug one or more appliances wherever you want on the outlet. The outlet also has an intelligent system that warns you when a surge may occur, with a red light located at the center. It indicates how much current you pulling and fills the entire area when a surge is likely to occur. Quite smart!
