Is the Primordial Soup Done Yet?
First, ``Nebraska''; second, ``San Francisco'':
[A very flat and uniform high-entropy distribution] [A very uneven and variegated low-entropy distribution]

States, arbitrarily numbered from 0 to 624, are strung along the horizontal axes; the vertical axes show how many instances of each state were observed in a sample of 460,800. (These are actually the distribution of 2x2 window configurations for the macaroni CA, at t=0 and t=50, respectively.)

[Thanks to John Beacom, who knows, for pointing out that Nebraska is actually flatter than Kansas.]
