Wow you figured out not every possible combination is -> useful <- all on your own? Here is your sticker.
Condescending sarcasm only works if you're actually making an intelligent point, otherwise you just end up sounding like a jackass. The point of my statement, in case it went over your head, was that there are 26 characters in the English alphabet, and 9 pixel patterns are insufficient to portray them all. Nice try anyway.
It should also be pointed out that the 2x2 lowercase font you're bragging about isn't 2x2. The h is 2x3; n, m, u and v are 3x2, s, t and y are 3x3... and those are just the ones I spotted in the first line. So yes, BS for a 2x2 font was correct.
Those fonts are readable in the same way grass is edible. Just because it's possible doesn't mean it's useful as a reading font. It can be used to convey information and the reader can with some adjustment get used to it. That is far from "perfectly readable." Reading anything longer than a paragraph becomes an exercise in masochism. They might be useful as a small machine readable font that needs to remain decipherable by humans, similar to OCR-A.
And just to demonstrate one can bold any font ...
Simply changing the color of text from grey to white doesn't make it boldface. What if the text is white to begin with? Boldface refers to using heavier weight strokes, which you can't do with your 3x3 font without making it unreadable.
people like you who know absolutely nothing about fonts.
So now you're passing judgement on the knowledge or lack thereof of complete strangers on the Internet, when your own demonstrated credentials are the presentation of the work of another person?
I'd normally refrain from this, but you did bring it up. I worked with 8-bit machines running CRT displays in the early 80s. Those displays are pretty low res and the built-in text patterns tended to use an 8x8 grid. To fit more information on the screen, I designed 7x5 and 5x5 pixel character sets. I also made one for 3x5 but I thought it was terribly ugly. I was 12 at the time. In high school, I was a writer and later editor of my schools' papers. In later years, I did a lot of desktop publishing work -- editing, layout and graphic design. I've also run an in-house press for one company.
None of that really matters, because the original point, which others have also raised, is that your friend's 3x3 font isn't very readable. Not unreadable, but definitely far from anything any reasonable person would describe as readable. Anyway, you have a nice day, Mr. Has-a-friend-who's-an-expert-on-fonts.
