The Interface
Reads You

Right now, this page knows how fast you're moving your mouse. It knows how long since you last scrolled. It knows what time it is where you are, and whether it's a weekday or weekend.

None of this requires tracking or cookies. These are the implicit signals that every browser provides — and almost no product uses them. What if the interface could sense your energy and adjust its atmosphere accordingly?

Move around. Stay still. Speed up. Slow down. Watch what happens.
