I'd prefer not to see hexagons. I've just made a general posting stating the following: "Hexa is the greek prefix for 6. Hexadeca is the greek prefix for 16. No hexagons (6 sided shapes) please unless they are somehow contributing to sixteen elements."
I'd be interested to see a variation which communicated connectivity. Perhaps connections between some shapes?
I don't quite like the font. Please try another one. Perhaps not italics?
