Arc Mastery

This one teaches Claude about motion arcs, the animation principle that keeps things from looking robotic. It covers why natural movement follows curves (joints rotate, gravity creates parabolas), different arc types from simple circular to complex S-curves, and how to apply them across UI transitions, character animation, and motion graphics. The practical bits are solid: add control points perpendicular to straight paths, use 10-20% of travel distance for subtle arcs, verify readability from camera angle in 3D. Worth having if you're doing any animation work where you need Claude to understand why a button shouldn't just slide in linearly or why a character's hand needs to follow a curve even when pointing straight.
