I'm Drying

This is a Do Not Disturb Sign for an Absurd Hotel. When you are traveling, what's the one thing that you often have to wash by hand? For us, it's the sock. Our Do Not Disturb Sign doubles up as a sock drying apparatus, speed up the drying process by spinning it. The drying process starts when you lock the hotel door, and blocks the entry/exit as long as the sock is not dry yet.
