Ask people to describe a brand they love and they reach for adjectives: calm, sharp, playful, serious. Look closely and most of those words describe movement, not pixels. Calm is a slow ease. Sharp is a hard stop. Playful is a little overshoot at the end.

Start with three curves

We define a brand’s motion with three easing curves and a duration scale, nothing more. One curve for things that arrive, one for things that leave, one for things that respond. Every animation in the system is built from those, so a menu on the website and a title card in a film feel related even when different people made them.

Constraints are the point. When a designer can pick any curve, they pick the one they like today. When they can pick one of three, the brand stays itself.

Motion needs a sound check

Before we sign off a motion system we play it on mute, then with sound, then on a bad connection. If it still reads as the same brand in all three, it is strong enough to leave the building.

Treat motion like type: choose a few good tools, learn them well, and resist the urge to demonstrate everything at once.
