This is a technical reference for Disney's 12 animation principles adapted for code implementation. It covers squash and stretch, anticipation, timing, and the rest with actual parameters like deformation ratios (20-50% for cartoony, 5-15% for realistic) and motion curve formulas. If you're building animation libraries, working with motion design systems, or need to explain animation concepts to other developers with precise technical language, this gives you the vocabulary and math. It's essentially a cheat sheet that translates traditional animation knowledge into implementation details rather than just theory.
