A pixel-for-pixel recreation of the font on TI-83 and black and white TI-84 graphing calculators, remapped to Unicode. There are lots of TI fonts already on FontStruct, but this is the only one that features the full set of 249 characters, including semigraphics characters. Everything that doesn't have a Unicode codepoint has been mapped to the Private Use Area starting at U+E000.
2023 UPDATE: Fixed line height and period/comma spacing. Found a few more homes for private-use characters as well.

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.
