Ellipse
=======

This demo shows a dynamic grid of ellipses whose horizontal and vertical dimensions are continuously swapped over time.
The class ``Canva`` subclasses ``anim.plane.canva`` and updates each ellipse in ``update`` using ``np.cos(t.step/20)``
so alternating cells animate in opposite deformation directions.
