Kinetics

By Csaba Kissi (Colorion), a searchable catalog of spring-driven motion instead of fixed-duration easing. Browse Interaction & Input, Feedback & State, and Surface & Motion demos, each with live stiffness and damping readouts. Interrupt a spring mid-motion and it keeps integrating from the current velocity. Every effect ships as plain CSS and React with no animation-library dependency, plus an AI prompt for dropping the motion into an app. MIT licensed.
