I actually have the beginning of a PostScript interpreter somwhere... 
And the core of a Joy interpreter is extremely small.  It's pretty much
'foldl compose . map interpretWord'.  Of course, I implemented a Joy
interpreter in the slightly sugared lambda calculus that lambdabot's
@eval module supports so...

(Crap, I actually want to find it (the PostScript interpreter) now.)
