Eigenvectors and eigenvalues
When a matrix moves the plane, almost every arrow gets knocked off its line. But a few special arrows stay on their own line and only stretch. Those are eigenvectors, and their stretch factors are eigenvalues. You'll hunt for them by dragging, discover matrices that have none, and compute them with a short formula. Then you'll find the axis of a spinning globe.
