As lines, things can move away and toward, or in a circle. A jagged, curvy line is still away or toward, and if it ultimately makes its way back it is a circle. A triangular path is still a circle, conceptually.
Three dimensional shapes can expand and contract, or both at the same time, perhaps in some cases in lines. The Sun sends its light and heat straight out, forever. But solar flares go up and out, then come back. Eventually, if memory serves, it is believed it will begin expanding in all directions, after which I assume some sort of contraction. Perhaps to a very small mass which then again expands in a supernova.
And there is a time aspect. There is continuous flow, there is intermittent, rhythmic flow, and there is randomly interrupted flow, all three in all directions.
And there is a quantitative aspect: sometimes things flow a LOT, sometimes less. There can be rhymicity or jaggedness to this quality–quantity becomes a quality–as well.
I have no idea what possible use these musings might be, but pass them along as they came to me.
