Will make more characters.

Version 2.6

Inspired by a comment by jonrgrover.

I built diamonds sized according to the Fibonacci series, then made a segmented display out of them. The design was then carved away to make the glyphs you see here. I used the members 1, 2, 3, 5, and 8. These sizes proved most feasible to work with in this sort of arrangement.

I gave the terminals a flared appearance which I think makes the glyphs look slightly Celtic. The design also makes me think of beach sand and things found on the beach - shells, pretty rocks, and so on.
