Diamond Signs (2012) (stanford.edu)

This is hilarious: one of those curious pursuits of an enigmatic genius.

My personal favorite diamond sign (one that Knuth has yet to cover) is the Patagonia wind advisory [0]; when we first saw one on our trip there we spent about half an hour taking various funny photos with it.

That looks like a Dr. Seuss hand reaching out of the ground and scratching the sky... creepy! Or are there palm trees in Patagonia?


Another interesting page from his website: http://www-cs-faculty.stanford.edu/~knuth/iaq.html


I think my favorite expression on these is may exist, as in "icy conditions may exist". I can't help but picture a sheltered tourist having a revelation about the physically possible range of climates.


Interesting; my mom collects the exact same thing, with the exact same rules...


Not related to anything in the post, but does it bother anyone else that those are called "diamond" shapes and not squares?
