I saw an Irish car whose registration ended 10110.
Mathstodon, please make my day and share photos of binary numbers in unexpected places.
@11011110 @christianp where do you get your shirts from?
@j2kun @christianp The binary one is from the gift shop at the Computer History Museum in Mountain View Calif. The polyhedron one was from a conference. The flowsnake was just some internet shop, I don't remember which one.
I can also recommend https://aperiodical.teemill.com/ — here's a photo of me in one of their shirts.
