Just discovered a incredible thing: probably the most famous number sequence in the world, the fibonacci sequence, produces unique forms. Sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34… Every following number is sum of two members before it. Try using numbers 1, 1, 2 or 1, 2, 3, or 2, 3, 5, or 3, 5, 8… You got the idea. However, if you change slightest detail (like use 8-13-22 instead of 8-13-21) the form will not look like anything else in the sequence. By the way, you can read more about this sequence by googling for "Divine proportion".
