I remember colleagues competing for the most 'interesting' one-liner in APL that actually did something useful, in university. 
I wrote several different kinds of simulator, one of which generated APL code on the fly that was then executed... plus a database-or-two. 
I've been actively collecting APL memorabilia and books for years now... if I could find an MCM/70 it would be awesome...

It's not just about APL, it actually has a downloadable copy of the source code. And it points to an executable version, apparently a packaged up Hercules running that code.

I recall Neil Lincoln (he of CDC/ETA) relating that he taught APL to his 
kids and his wife (APL was pretty much a natural for the STAR) as a 
first programming language. 

I took some time to learn it fairly well, but never really had any 
opportunity to use it much, so it's gone into the memory dustbin of old 
never-used languages of my brain. 

A co-worker back when would never use the name of the book or the 
abbreviation. He always referred to it as "that Iverson language" or "TIL". 

And it's comparatively easy to write short, perfectly opaque code in 
APL; probably more so than other common languages.
