This is a font containing every Latin, Greek, and Cyrillic letter I could find.
GlyphLandyn/Lilly is a sans-serif, pixel optimized with monospace Latin, Greek and Cyrillic letters and PUA (Private Use Area) characters. The  Object Replacement Character is a full square.
This font also includes Thai characters and Linear B Syllabary.

The font used on the TI-84 Plus calculator I sometimes take to school to use it for math.
I added Greek and Cyrillic letters
Capial theta, sigma, lowercase mu, and lowercase pi are not custom characters. I extracted them from the calculator.
I had to take the calculator to make these letters. I had to extract these from the calculator.

Finished! (Took me 3 days)
Private use characters are encoded in Variation Selectors and Latin Ext. D.

Based off of a puzzle game Idea I have.
It's sort of like a cross between Gunpey and a 1-D Sudoku.

Version 1.1
*
A font designed and optimized for writing very small and dense math equations, especially those related to ESOSVM. This should make cramming equations onto a small canvas much easier.
I included A-Z and a-z so you can write with the font or use the letters to declare variable names. So it isn't just a "pure math" font like most other mathematics fonts I have seen around.

DIAGRAMMING PIECES
These are still being drawn and tested. The sizes these have to be will depend on the sizes of all other glyphs, so these pieces will be made last.

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.
