munching squares
(foldoc) | munching squares
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.]
