Design: environmental & neat

This will be super useful in my house. The place I stay is pretty old. Sometimes, without paying attention of the electricity usage, 跳電 occurs. So, we have an unwritten rule in the house: before you start to blow dry your hair, LISTEN!! And, sometimes, I have the rush when I "got" the right to use my hair dryer; and opposite rush when I hear the dryer goes on in the other room while I reach for mine.

THIS potentially allows me to see, if the line can hold up to 2 dryers :).
