A programming language, programming-linguistically close to PostScript and Lisp.
It was designed by Brian Connors and Chris Pressey, with Mark Shoulson helping with some linguistic details.
So, what makes it so special?
It's a language that is based on the Klingon language, and is meant to be something like an example of how Klingons would program their computers.
