This one's about combining animation principles rather than learning them in isolation. It walks through how principles interact: squash and stretch paired with timing for volume preservation, anticipation matching follow through for rhythm, secondary action supporting staging instead of fighting it. The approach is practical, showing how easing applies along arc paths and how timing windows dictate deformation intensity. If you're past the basics and wondering why your animations feel disconnected even when individual principles look right, this covers the interdependencies that make movement cohesive. Short at 42 GitHub stars, but the synergy framework is solid.
