Now I wouldn't have thought to ask: Which way is yellow stripe moving!

Deep thought!

Is the yellow stripe being pushed off the canvas by the black or is the yellow stripe pushing the black off the canvas?

That’s exactly what a group of students were learning about when I walked into the gallery. Too Bad I never got to sit in on the whole lecture!
