I have done text formatting in Postsrcipt. You feed it a paragraph in the form 
of one long string and it performs linebreaking, indenting &c for you. Very 
handy if you have a section of text to be put on a slide and do not want to
redo the slide in FrameMaker or wha'ever.

I also have done number to text translation in PostScript, that is, 123 gets
translated to One hundred and twenty-three.

Both of these tasks are most arguable done better with a compiled program of
some sort, but in both cases i wanted complete solutions in PostScript.

I was sure I'd seen a Turing machine simulator in postscript, but I can't find
any references to it now. Has anyone seen such a beast?

Sun's Network Extendable Window System (NeWS) is an object-oriented
multi-threaded client-server window management system that allows you,
the user, to write whole applications in Postscript and C, C++, whatever,
mix and match as you like.  There's a GUI developer (GUIDE) and a user
toolkit (TNT).  There are several demos included with SunOS, and if you
can ftp there's HyperLook and SimCity on uunet.  SimCity in Postscript
is neat!

Take a look at Sun's NeWS environment.  The majority of our
application is written in PostScript (30K+ lines of code).  Just
think, object oriented PostScript, complete with meta classes. 

Neat, huh?
