Are the Toynbee tiles a thing outside NYC?

I was thinking about them earlier, and then I saw one at Union Square

I had to google was this was. (Lifelong westerner here.)

They're very weird tiles that show up in the street and on the sidewalk

As far as I know, there's no real idea of who is doing it or hoe

How

i listened to a podcast about it once! a lot of the ones here in nyc are copycats and not the originals, i believe those popped up in the early 90s or late 80s

and i feel like they're in a few other major cities as well but i could be totally mistaken

i used to see them all the time when i worked in chelsea and occasionally still notice them when walking in manhattan

That's cool! I've mostly seen them in Lower Manhattan
