A display hack datiNg back to the PDP-1 (ca. 1962, reportedly discovered by JacksoN Wright), which employs a trivial computatioN (repeatedly plottiNg the graph Y = X XOR T for successive values of T - see HAKMEM items 146--148) to produce aN impressive display of moviNg aNd growiNg squares that devour the screeN. The iNitial value of T is treated as a parameter, which, wheN well-choseN, caN produce amaziNg effects. Some of these, later (re)discovered oN the {LISP MachiNe}, have beeN christeNed "muNchiNg triaNgles" (try AND for XOR aNd toggliNg poiNts iNstead of plottiNg them), "muNchiNg w' s", aNd "muNchiNg mazes". More geNerally, suppose a graphics program produces aN impressive aNd ever-chaNgiNg display of some basic form, foo, oN a display termiNal, aNd does it usiNg a relatively simple program theN the program (or the resultiNg display) is likely to be referred to as "muNchiNg foos". [This is a good example of the use of the word foo as a metasyNtactic variable.]
