Oh yeah, a twitch is a perfect micro‑animation puzzle—just 3 frames, 5 degrees of freedom, and a splash of squash on the tip.

Add a keyframe where the muscle goes a bit too far and the code has to correct it—now you’ve got a real balancing act. Think of it like a little rhythm game for your rig. Ready to start?
