Comment A Programming Language (Score 1) 191
There is APL ("A Programming Language"), which I remember getting some limited use (not by me) on campus when I was an undergrad. The language was sufficiently greek that it used some Greek characters as part of its language; I think the aim was to design a language programmed by mathematical notation. The keyboards for APL also came with stickers on the keys so that you knew which keys to chord in order to generate the non-standard language constructs. It looked like a very symbolic programming language to me. And I was scared of its keyboards.
