@pixelambacht So, it's a font with 256 ligatures, each ligature represents a number from 0...255 and the resulting character is a binary representation of that number? Could actually come in handy for some programming tasks.
I had been thinking of making a font that would do the opposite: make ligatures of all combinations of 8 zero's and ones and show the digital number instead or on top of it. (Could find if it already had been done.)
