And here's a segmental display font.
Actually, this is an old font I made in some of my unshared projects on Scratch. I just decided to complete it. No already existing characters were edited, aside of the D because it was looking to much like the O.
The black box is nothing really, it just serves as the height-setter and is placed on the unnamed character placed after the ~ in unicode.
So here it is!
(And here goes a new font!
This font may be weird-looking, indeed, but it has this particularity to be read the same even if mirrored (if you put the mirror just below the text) as each single glyph is symmetrical following the X-axis (the baseline).
The R, the lowercase Y and some of the numbers were true challenges but I had fun doing them all anyway.
I wanted to do an ambigram-ish font and here it is. Well, good luck trying to do an actual ambigram out of this but this could surely be helpful for a number of other things. You to choose!
EDITS:
1. Improved the $ and tried to improve the Y/y.
2. Re-improved the $ and the Y/y, also improved the U/u and the n.
3. Improved the 2. And edited a bit the b and the h.
4. Improved 1 and 7.
5. Edited the F and the y for them to look less "out" of the font. (May not being an improvement.)
