Evans, mathematical font from GEOS FontPack 1.  In case you want to write formulas.  Minor kerning, digits will fit comfortably under the square root's horizontal.

Inspired by Neoletters.

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.

GS Unicode is a project I'm working on so (almost) all languages get support!  With 14,564 non-spacing characters, this font is finished (as of Unicode 13.0, and as of FS's pre-July 2021 glyph inventory).  Please tell me if some of the characters aren't working.  I'll try to fix them as best as I can!  ...And now, with a new glyph inventory comes a new age....Stay tuned for more updates.

Latin block is traced from Linux stock VGA8 font. Designed to fit 8x8 grid including spacing, so most symbols are 7x7 =WARNING= Line spacing is stuck and cannot be edited within FontStruct, you can edit it manually, see http://designwithfontforge.com/en-US/Line_Spacing.html for example.
