Munching Squares -- from Wolfram MathWorld

A plot of the cells on a grid satisfying bitwise XOR(a,b)<n for consecutive values of n=1, 2, . It is thought that it was discovered by Jackson Wright on the RLE PDP-1 around 1962 (Beeler et al. 1972). The plots above show the results in static and animated form for n=1 to 15 on a grid running from 0 to 15.
