Back to hexagons today. There's something really exciting to me about the relationship of shapes to one another, especially when there's some space between them. Like Miles Davis said, "Don't play what's there, play what's not there." Rather Zen, don't you think? Actually, it's rather Taoist... Here is my favorite chapter from the Tao Te Ching:
Tao Te Ching - Lao Tzu - chapter 11
Thirty spokes share the wheel's hub;
It is the center hole that makes it useful.
Shape clay into a vessel;
It is the space within that makes it useful.
Cut doors and windows for a room;
It is the holes which make it useful.
Therefore profit comes from what is there;
Usefulness from what is not there.
