But this seems like an interesting project. It seems interesting because it approaches the problem of a typeface from what seems like the same rules I have about type: Readability, and Legibility. I however cannot divorce myself from emotion and attitude in type, and I judge typefaces also on aesthetics.
Dyslexie does not concern itself with aesthetics. It has a more noble cause. It is a typeface that tries to accomplish a simple goal: Make a typeface that is easily read by people with Dyslexia.
When they use it, they make fewer errors whilst they are reading. It makes reading easier for them and it takes less effort. The Dyslexia font is used by several schools, universities, speech therapists and remedial teachers.
