Nice. You've managed to be fundamentally a lot terser than my version, probably by not generalizing so much. Yours can still be golfed down a good bit by using the usual dirty tricks, of course (like, using the trinary ?: operator instead of regular if/elsif/else blocks), but it's already about half as long as mine and probably more portable to boot :-)

    you mean, something like this? :) 
    use Storable 'dclone';for$y(0..23){$l[$_][$y]=int(rand 7)?0:1for(0..79
+)}while(1){@f=@{dclone\@l};print"\033[2J";for$y(0..23){for$x(0..79){p
+rint$l[$x][$y]?O:" ";$n=0;for $h(-1..1){!$_&&!$h or$n+=$l[($x+$_)%79]
+[($y+$h)%23]for-1..1}$l[$x][$y]?$n<2||$n>3?$f[$x][$y]=0:0:$n==3?$f[$x
+][$y]=1:0}print$/}@l=@{dclone\@f};sleep 1}

      Yeah, something like that. I managed to save another dozen strokes, though...

      use Storable 'dclone';@l=map{[map{int rand 7?0:1}0..23]}0..79;while(1){@f=@{dclone\@l};print"\033[2J";for$y(0..23){for$x(0..79){print$l[$x][$y]?O:$";$n=0;for$h(-1..1){!$_&&!$h or$n+=$l[($x+$_)%79][($y+$h)%23]for-1..1}$l[$x][$y]?$n<2||$n>3?$f[$x][$y]=0:0:$n==3?$f[$x][$y]=1:0}print$/}@l=@{dclone\@f};sleep 1}

      It's probably possible to do still better by devious means, but that's as short as I can make it without changing the logic. I'm not really a golf pro.

    or indeed my version, but it's a hell of a lot more portable!
