Delightful UI animations by understanding the brain
summary
Claim: the brain’s motion center (MT / V5) and its smooth pursuit and global-motion heuristics explain why some UI animations delight and others annoy. Demonstrations show saccades, pursuit, and vector crowding; the builder creates react morph — a hook-based FLIP-backed prototype that clones DOM nodes and animates them with springs — and it runs live in demos and is published minutes before the talk, so the technique works end to end using FLIP animations and physics.
