I hope this question doesn't seem too archeological...

I am trying to find the algorithm for the Munching Squares
graphics hack.  This was, I believe, originally done on a PDP-1
at MIT in the early 60's, and has been used as a graphics demo
on some more recent hardware (MicroAngelo graphics board,
Lisp Machines, etc.).

I remember that the algorithm consisted of some clever
XOR'ing of a seed value with the contents of your graphics
memory, but I can't recall any more than that.

Any help would be appreciated.

Thanks,
Bill
