Who's using Processing?

Processing is a computer language for producing graphics and animation; it is easy to use (although I am still trying to understand colors and text fonts), but talking about it is difficult.  A conversation may go something like this:

Bud:  Have you heard about Processing?
Lou:  Have I heard about processing what?
Bud:  No, have you heard about the Processing language?
Lou:  The processing language for what?
Bud:  I mean the language Processing.
Lou:  What language processing?
Bud:  The language called Processing. It is a graphics language with a syntax similar to C.
Lou:  A syntax similar to see what?

[ Bud and Lou are the first names of comedians Abbot and Costello, their "Who's on First" is a classic comedy routine.]
