Just for the people who are probably really confused now... my other online nick has the initials BF. He always calls me that. Rollseyes When I equated symmetry and harmony and beauty, I was thinking of the other type of symmetry. I should have been more clear. Asymmetry is of course, more concerned with harmony than exact symmetry is, and yes, asymmetry is a type of symmetry. Sort of. g A beautiful explanation, Ian, thanks.
