Comment:

 Michael, could I get your mathematical expertise here?  If I read 256
 random bytes from a true random number generator, what's the probability
 that I receive less than 64 unique values *five times in a row*?  That
 seems pretty unlikely to me.  It's almost like all the molecules in the
 room jumped over to one quarter of it and stayed there for 5 observations.
 Almost.
