[math-fun] Re: really bad random number generators

No surprise there. A similar thing happened to Gary Demos back at triple-i (ca 1975). He was making pictures of simulated galaxys, using fortran's random number generator, and kept getting really clumpy pictures with lines of stars. Later, with a better random number source, the same algorithm produced very nice galaxys. Rendering the random number sequence graphically really made the shortcomings visible.
