I came across this news item today:

http://www.theregister.co.uk/2013/01/25/arabic_programming_language/

It seems on-topic because of one specific characteristic of the language mentioned in the article:

By varying the lengths of the lines that connect the Arabic letters that make up the language's commands, Nasser can reshape the appearance of his code without altering its function, producing programs that are both practical and artistic.

The means by which that feature is implemented using ordinary Arabic typefaces, though, may clash with the use of more authentic Naksh typefaces which already have kashida.
