The Doorknob Signal By Yanko Design

We’ve seen it before, the universal sign of “I have company, go away” signal. Often taking form as a tie around a doorknob or the potted plant flipped over.The Doorknob Condition uses an innovated pulley system that makes the knob on the exterior recess inwards when pulled from the inside. Unfortunately, this is only available in Hotels.
