Thoughts on a Button
Recently at the museum, I saw a group of geometric portraits by the artist Walter Dexel. Looking closer at one of them, something jumped at me:

Can you see it? the shape on the striped shirt "feels" interactive - it's a close button!
I believe most people today will first parse this shape as a "close button" and not a "clothing button". It's interesting to think that when the painting was created in 1933, the meaning that seems so natural today did not even exist.

This also caused me to wonder where the UI element's name "button" may have originated - obviously, machines have physical buttons as well, but are they linguistically related to clothing buttons?
Well not directly, but they share a common ancestor - the french bouton, meaning bud, protruding knob or something that sticks out.
That's it, just thought it was interesting.
