    NAME
         munch - munching squares screen hack
    
    SYNOPSIS
         munch  [-display  host:display.screen]  [-foreground  color]
         [-background  color]  [-window]  [-root]  [-mono] [-install]
         [-visual visual] [-delay seconds] [-xor]  [-noxor]  [-shift]
         [-noshift] [-logminwidth minimum width]
    
    DESCRIPTION
         The munch program preforms the munching squares  hack  until
         killed.   It  picks  square size, position, and gravity ran-
         domly; configurable options are listed below.
    
         The munching squares hack cosists of drawing Y = X XOR T for
         a range of X and T over and over until all the possible com-
         binations of X and  T  have  come  up.   It  was  reportedly
         discovered by Jackson Wright in 1962 and took 5 instructions
         of PDP-6 code.
    
    OPTIONS
         munch accepts the following options:
    
         -window Draw  on  a  newly-created  window.   This  is   the
                 default.
    
         -root   Draw on the root window.
    
         -mono   If on a color display, pretend we're on a monochrome
                 display.
    
         -install
                 Install a private colormap for the window.
    
         -visual visual
                 Specify which visual to use.  Legal values  are  the
                 name of a visual class, or the id number (decimal or
                 hex) of a specific visual.
    
         -delay seconds
                 How long to wait before starting  over.   Default  5
                 seconds.
    
         -xor    Use the XOR drawing function.  (Default.)
    
         -no-xor Don't use the XOR drawing function.
    
         -shift  Start drawing the square at weird  starting  points.
                 (Default.)
    
         -no-shift
                 Don't shift and start drawing the  square  at  weird
                 starting points.
    
         -logminwidth minimum-width
                 The logarithm (base 2) of  the  minimum  with  of  a
                 square  (must  be a power of 2, or some parts of the
                 square aren't.)
    
    ENVIRONMENT
         DISPLAY to get the default host and display number.
    
         XENVIRONMENT
                 to get the name of a resource  file  that  overrides
                 the  global resources stored in the RESOURCE_MANAGER
                 property.

    HISTORY
         Quoted from HAKMEM, for historical interest.  As that  docu-
         ment  says,  "Unless otherwise stated, all computer programs
         are in PDP-6/10 assembly language."
    
         ITEM 146: MUNCHING SQUARES
                 Another simple display program. It is  thought  that
                 this  was  discovered  by  Jackson Wright on the RLE
                 PDP-1 circa 1962.
    
    
                          DATAI 2
                          ADDB 1,2
                          ROTC 2,-22
                          XOR 1,2
                          JRST .-4
    
                 2=X, 3=Y. Try things like 1001002 in data  switches.
                 This  also  does  interesting things with operations
                 other than XOR, and rotations other than  -22.  (Try
                 IOR; AND; TSC; FADR; FDV(!); ROT -14, -9, -20, ...)
    
         ITEM 147 (Schroeppel):
                 Munching squares is just views of the graph  Y  =  X
                 XOR T for consecutive values of T = time.
    
         ITEM 148 (Cohen, Beeler):
                 A modification to  munching  squares  which  reveals
                 them  in  frozen  states through opening and closing
                 curtains: insert FADR 2,1 before the XOR.  Try  data
                 switches =
    
                          4000,,4    1000,,2002    2000,,4    0,,1002
    
                 (Notation: <left half>,,<right half>)
    
                 Also try the FADR after the XOR, switches = 1001,,1.
