Of course, you cannot completely fill this container by pouring into it,
since the speed of light constrains how quickly the paint can expand outward
at the bottom/side of the container.  The container can hold enough paint to
paint the entire surface (given the standard abstract paint), but the act of
painting it would take forever.
