The other numbers jumping up and down looks weird, but you can still tell which is which.
Artistic lettering, that might be ok for Herman Hesse and his tinkered typewriter and his letters to beloved ones, but it isn't good to read after all.
That you still can read the numbers is rooted in the numbers itself, even if not latin absolutely constructed to be read well under any circumstance.
Likewise the latin letters you can cripple them, you can mirror them, you can turn them upside down, they can be washed out by centuries and are still clear to read even if 2/3 is missing.
Do such with any else letters it isn't possible!
Forget a shitty dot in arabic and it means something complete different, you can l a v a w y hlf o txt ad y sill cn rd and it won't lose it's meaning.
No matter who invented it first - imho it wasn't the persians, american natives had a logical lettering system long before, it was just not to store text it was to store musical notes, but what makes the difference is the comprehensible system behind and not the difference in purpose, neither if them are knots and spaces in yarn.
What makes a letter to a letter is the comprehensibility and its logic, that i can construct a word, sentence by use of always the same system, not "oh i forgot a dot and now it means something different".
That little me from deep valley in switzerland can communicate with you and you will understand me even if i forget something or write something wrong.
Else yes the font is good to read and true zero is a slight disappointment.
Sorta "helvetica" i actually didn't remember who designed this font last century, but he removed the serifs and gave the letters a clearer to differ look.
It was if i remember this right, the same dude who designed most of the traffic signs (mostly our swiss ones, other countries have different but compare them they are all less good designed, less clear in their meaning, he was a huge designer even if it's not obvious and that he was infamous to public but exactly this makes it so good, decency.
The goal was a different one, my master was a chemist, old school, he did that to lead humanity in a better age, now it's done to boast the ego and to get rich and famous. It was as i guess the reason why he quit, he didn't talked often about his reasons to quit his job, but it has something to do with the sellout, the changed goals after WWII, the rise of bachelors and other parasites. In his words "we did many without to have long time experiences, we put it on the market and had no idea what the result in a long run will be" a thematic which is since a while actual again was "radical elements" not that he made a big thing of that "any cow eats it with the hey, it can't be that harmful", but there must have been a good reason why he (co-) invented "selgine" which was a toothpaste containing only the natural mineralisation from sea salt. Neither about this he liked to talk to much i can't tell exactly if he invented it or was just part of a team, his understatement was fairly big. What a difference! To be a genius but not to boast with. "i'm just a goats herder from Toggenburg" - "smell it Gernot on what reminds you this?" that's how i learned chemistry from him, because you won't forget what you smelled and due to correlation you will always remember the words as soon as you smell a substance, clever lad).
Sure he won't be pleased with numbers jumping up and down, this contradicts to the idea of "helvetica".
A stroked zero has a good reason.
Well, and to some this "0" is zero and to others "o", oh boy! awe 2!
