One week in Paris. Eight senses. Thirty-four episodes. Most people visit a city. I wanted to read one. Not the monuments or the restaurants, the logic underneath them. Why the bread sounds the way it does. What a hotel that has a position feels like to sleep in. What you taste when there's nothing to look at. This is that week, organized by sense. Start anywhere.

We tend to think of taste as a closed-loop system between the mouth and the nose, but the physiological reality is far more "wired." There’s a new frontier of sensory design. We are seeing the collapse of the wall between what we hear and what we consume. Products like the Lollipop Star are turning candy into a hardware device, using bone-conduction to play music through your teeth while you taste the flavor.
