It always seemed to me that space evokes tension. The tension then is illustrative or expressive, relative and usually needs a part of some form it relates to. They together create a picture, meaning or something we like to look at for a reason we often don’t need to understand (we can discover).
So it seems that the world we perceive around us, which is happening in pictures for the more meaningful part, and regardless of the kind and time of that world, is packed with relations between the elements of form and space. That’s the one that is never empty.
