It didn't occur to me until I read your post Mike... but what is
quickly becoming my favorite multi-purpose development language all
started with a paper headed by Erik Meijer, et Al. entitled
"Programming with Circles, Triangles and Rectangles"

http://research.microsoft.com/~emeijer/Papers/XML2003/xml2003.html

At various stages and in various pieces the language concepts
presented in this paper have been known as X#, Xen, and Polyphonic C#.
 These have since been absorbed into what seems to be the next
generation, at least from MS's perspective, in the C-based family of
programming languages: COmega > http://research.microsoft.com/comega/
