He smiled. Then he opened a new file. He had an idea for a fox. Not a goblin. A fox that could run, leap, and curl into a perfect, sleeping ball. Forward Kinematics (FK) and Inverse Kinematics (IK) are

But his greatest creation wasn't Grunt. It was his new rule: IK is like a robot arm—grab the hand and the rest follows
"The best tools," she said, "are the ones that disappear."
