Motion systems that still feel human after the tenth release

Rules that survive release ten

Motion systems fail slowly. Each release adds a new curve, a new duration, and a new exception, until nothing feels related.

We write motion as a short rule sheet with a small set of curves, so the tenth release feels like the first.

Keep it human

Slightly slower, slightly softer, and never in the way of the task. Motion should feel like a considerate person holding a door.
