no nigger i already invented the new system you can't go back now.
it's just a block of text but instead of using regular characters only special characters that are easy to draw, paint, stencil and OCR recognize for example:
"^+=ETYUIOSFHJKLZXCVN<>" are easy to produce and recognize
on other hand:
"@,&" are hard to stencil or draw and / or may be hard to recognize at low resolution
remember also that most characters have have 8 different orientations because they can be rotated by 90 degrees 4 times plus mirrored. each of 8 orientations can count as a separate character.
and i only used as examples characters present on my keyboard but you can pull numbers, letters and special characters from all languages such as ancient greek, japanese etc.

some new characters can be created as well.
we could easily have, say 256 easy to create and reliable to recognize characters ... swastika could be a character for example, and we could also have a separate swastika that spins in reverse direction ... or we could have letter "H" but horizontally on the side or letter "S" but mirrored etc.
so one character is 8 bits then and a 30 x 30 matrix of 1-bit dots is replaced with a 12 x 12 grid of these characters.
