They certainly did. The SFMTA also showed these to me and explained that not only were they extremely temperamental, but it also cost about $3k to print one of the curtains with the special barcode that prompts the curtains to rotate.

I would love to build a programmatic version of this font defined by an array of shapes (full square, triangle, rounded corner, pizza, and notch), and rotations, but I think even that would be a somewhat offense of the license, so I'm not going to publish it.
An array of those would spell out most of the symbols. Some of her characters violate this pattern though so it only approximates most of the symbols.
If lilsneddz responds with yes, I'd love to publish the code so people can make public interactive displays with her font design.
I think a system like this would make it easier to prototype lowercase and other international symbols though!

Are you joking? this sounds sick. Please go ahead!!! I think I need to update my website so it's more clear how open this is, haha!
yawnxyz
wait really?? ok!! I thought I would actually build a typography editor around it, maybe if you click a cell it would rotate symbols and/or orientations. Open source of course!
This is what I'll do instead of spending time with family over thanksgiving :P

Typography nerds are some of my favourite nerds.
Font specimen pages are so often screaming with design language and intention, they push and prod to evoke and present.
Maybe the secret has something to do with the lack of priority to the actual content; just present the font gosh-darn!
Looks nicely executed within the confines of the inspiration. very cool

Andrew Glassner's Notebook: Recreational Computer Graphics is a really neat book (I especially like the tiles that can add numbers). The author's site is https://glassner.com/computer-graphics/
Chapter 6 in the book ( https://archive.org/details/andrewglassnersn0000glas/page/98... ) Signs of Significance starts with 7 segment displays to the 14 segment and 5x7...
He then goes on to the 66 segment Vienna underground font and an 83 segment font he saw in an elevator at a Siggraph conference in Orlando ... and then concludes with his own 55 element mosaic.

Also, Adam Savage's Tested - https://youtu.be/eKCcqlJnZcA (3 days ago) looking at https://www.kellianderson.com/books/alphabetinmotion.html
At 7:00 into the video is C & D pages looking at the modularity of a font.
(the section "U & V" about 3/4 down the page has the modular components for Kombinations-Schrift https://www.moma.org/collection/works/2724 which was also looked at at 22:00 into the video.

As a native that absolutely cringes at "San Fran" ... I still got mad respect for that awesome name. Well done.
lilsneddz
Hey, I made this font. I really ummed and ahhed over the name for this exact same reason. But in the end it was just too clever to pass up. Thanks for moving past it, haha.

I've always found that cringe to be a strange shibboleth. AFAICT everyone has to summarize with the bay area instead, which I find even more comic having grown up on a coast, aka a bay area.
adastra22
The bay area is more than SF. If you mean San Francisco and don't want to say the whole name, you use either 'SF' or 'the city.'
I'm not sure why it's a strange shibboleth? Not every name has to be shortened, and if you are going to shorten names, not every short form is acceptable. I don't know where "San Fran" came from, any more than "Cali", neither of which are used by locals, but it just doesn't feel respectable. It's not the name of the city.

"SF ... It's not the name of the city."

It’s funny how most SF posts will have an “as a native” say that. You don’t really get that from London as much. Strangely parochial attribute of the culture. I wonder which other cities have such populations. NYC has a big “transplant” vs. “native” thing going on so maybe it’s just American, but I think people do it in Vancouver too. Though Canadians just kind of copy Americans for the most part.
I’ve taken to calling the city San Fran as a result. Sometimes I enjoy a good EssEffOh or Frisco too. Really gets the audience going.

I'll be sure to call it "Frisco" instead.
+1 on the awesome name though.

That's fine, it's what people from the east and south sides call it.

FYI no lower case, also "contact the author for licensing". (The article is a neat story of digging into the history of the displays which are about to be going out of service, as well as some practical aspects of the font design - it's just not casually available.)
lilsneddz
Honestly, I wasn't expecting this font to go anywhere, and then the SF Chronicle reached out, which has been lovely. Anyone who emails me can have a copy, I just haven't made an easy download link. I've thought about it since, but actually it's way nicer to hear from people and hear about what they're making. It is a community-driven project, and this slower form of distribution feels closer to my original intent. :)

This post ends with a beautiful poem set in Frans Sans
OUTSIDE MY LIFE, INSIDE THE DREAM.
FALLING UP THE STAIRS, INTO THE STREET.
LET THE CABLE CAR CARRY ME.
STRAIGHT OUT OF TOWN, INTO THE SEA.
PAST THE DAHLIAS AND THE SELF-DRIVING CARS.
THE CHURCH OF 8 WHEELS. THE LOWER HAIGHT BARS.
THE PEAK HOUR SPRAWL. THE KIDS IN THE PARK.
THE SLANTING HOUSES. THE BAY AFTER DARK.
MY WINDOW, MY OWN SILVER SCREEN.
I FOLLOW WHERE THE FOG TAKES ME.

I appreciate that the author talked to various people (technician, engineer) and visited the shop rather than just doing online research. It's rare for people to go to the effort of in-person research.

There are higher detail versions of these LCD displays like those used on the NJ Transit Comet cars: https://www.flickr.com/photos/recluse26/286211358/
Should be possible to get a passable @ on those.

> Back at the SFMTA, Armando told me the Breda vehicles are being replaced, and with them their destination displays will be swapped for newer LED dot-matrix units that are more efficient and easier to maintain. By the end of 2025 the signs that inspired Fran Sans will disappear from the city, taking with them a small but distinctive part of the city’s voice.
:-(

If the dot-matrix is fine enough, you could still render any font properly. Plus you can add emoticons :)

I have seen these throughout the US and Europe and been fascinated by them. Penn Station has (had? been a while) a big one with more segments per character. I’ve been trying forever to find the name of this particular style of segmented displays and get more info on them. The closest I could find is “mosaic display.”
Love this article!

When I was last at Penn Station in the 2010s their departure board was a mosaic LCD like the article, not a split-flap display:

I do miss the split flap displays at the Boston and Providence Amtrak stations though…

It's probably Reitberger's 38-segment AFA alphanumeric LCD:

https://www.reitberger.de/English/Broadsheet/Prospekt_GA_AFA...
These are very common here.

I am not expert but I really like the font. It does a lot for such a primitive display. Makes me wonder why we used to have those bad 80s 90s alphanumeric LCD displays in most places too cheap for pixels when they could have done this.

Beware that pressing the back arrow twice takes you to unexpected naked photos.
seniortaco
Are they naked photos you've seen before?
crazygringo
This is the second comment I've seen on HN today about the back button having unexpected results on a site.
I'm so confused -- I use Chrome on a Mac and my back button works entirely normally. No naked photos, sorry to report.
Is this a real thing that Chrome isn't susceptible to? Or are people just making jokes?

NSFW, obviously, but also not all that titillating. (It's artsy B&W photography of women in their bathrooms.)

They mean the left arrow key on your keyboard.

When I was a child the front side displays on new Muni buses used to use these probably solonoid driven LED arrays. If you sat under one you could here this clattering sound that sounded kinda like rain each time the display changed. This discussion is bringing back old memories of those.
The older Breda trains and I think buses also used to use backlit paper rolls for signs: https://upload.wikimedia.org/wikipedia/commons/4/4c/T_Third_... Those were significantly more readable
