OK, so I started this back in 2008 (then called "test1") with 4 letters, then forgot this site existed until tonight in 2023. I worked on it some more for a couple of hours and here it is. Missing a few glyphs but I will save those for a later improvement. :) Very beginner-y, because I was just playing around when I started it. But I kind of like it. It's quite readable at tiny sizes and makes me think of some old 1990s Wired Magazine fonts or early blog fonts.
₫€®¡$¤r¥:©¤₦₡€₧:¤₣:℗®¤_¤₣ I meant : 1. it's not a font because of the number of duplicates; 2. internet search engines believe the contrary (we deserve smarter crawlers); 3. it's an unfinished work (I felt lazy for not designing the filters beforehand - 2x2 grid combinations); 4. I'm unsure about the final license, esp. when I have released a sub-pixel '''''font''''' with the same method.
