I am generally not a fan of turning public infrastructure into advertising spaces, but I'm willing to make an exception for this ad on an Oslo bus for the world accordion championship.

Articulated buses are commonly nicknamed "accordion buses" because of the flexible, ribbed bellows connecting the two cabin sections. 

The bus in the photo features a large graphic of a Roland accordion being played by a giant pair of hands. The two halves of the accordion are on either side of the flexible section, so that it looks like the bellows of the instrument. When the vehicle turns or maneuvers, the real bellows compress and stretch, making it look like the instrument is actively playing.

Above the windows is the text "VM på trekkspill, 16.-22. oktober i Asker Kulturhus" ("World accordion championship, 16th-22nd October in Asker cultural centre")

Why do design patterns often fail to have an impact? How might we remedy that? The paper I wrote with Chris Kohls for the PLoP 2025 conference,"Patterns and their Umwelt: How to Make Patterns Come to Life" wirfs-brock.com/rebecca/pape... offers advice for writing, maintaining&evolving patterns

I’m doing a thing! I don’t think the problem with Democrats is our policies, or that some of us are trans. It’s that too many Democrats are desperate to be liked by people they look down on. I don’t look down on baristas: I was one. I hope to be of service again.

I am running for Congress to fight for our country. I’m not here to be polite – I am here to stand up for the working class. Together we’ll prove what should’ve been obvious all along: trans people aren’t political props - we’re leaders. Visit bethfordemocracy.com to learn more about our campaign!
