Great obfu. Funky!

Just as a matter of curiosity I tore into it and made a few modifications:

  • Pushed everything that is to be printed into an array so that the script could get away with only one print, with less processing inside the print function, for a little better (maybe?) output efficiency.
  • Changed sleep 1 to select, with a timeout of .2 sec., for smoother action without loss of synchronization.
  • Golfed it down as much as I could without changing logic, flow, or behavior. Saved 82 keystrokes.
  • Reformatted script for seventeen full lines and one partial, plus the shebang.

Here's the result:

#!/usr/bin/perl sub r{int rand pop}++$|;@g=map{[map{' '}0..$=]}0..25;my$j=pop||2+r 3; @f=map{my$k=my$n=$b++;my$z=1;my$x=r$=;;my($q,$v,$e)=my@l=(0x4);my$h=r 9;$w={i=>sub{$k=r$j while$k==$n or!$f[$k];my$o=$f[$k];$h+=$e?-1:1;if( $h<1){$e=0;$k=$n}$e=$h>6?1:$e;if(!$z){my$u=$x<$$o{x}()?1:-1;$u*=$e>1? -1:1;$q=$e?$u*r 7:0;$q||=4if$e>1;$v=r 6 if($e&&r(7)>3)}my$t=($$o{z}() cmp$z)+1;$t=0if$x==$$o{x}();my$s=$x<$$o{x}()?1:0;for(0,2){$l[$_+$s]+= $t cmp$l[$_+$s]}for(0,2){$l[$_+($s?0:1)]=0}$v-=2if$z;$x+=$q;$z+=$v;$z =0if$z<0;if($x<2){$x=2;$q*=-1if$q<0}if($x>$=-2){$x=$=-2;$q*=-1if$q>0} if((abs($x-$$o{x}())+1)*(1+abs($z+1-$$o{z}()))<9){r 2?$$o{c}($n)||($e =1):${$f[$n]}{c}($k)}},d=>sub{$g[20-$z][$x]='O';$g[21-$z][$x]='+';$g[ 22-$z][$x]='|';for(0,1){my@c=$_?qw!/ - \\!:qw!\\ - /!;$g[21-$z][$x+($ _?1:-1)]=$l[$_]?'-':$c[2];$g[22-$z-$l[$_]][$x+($_?2:-2)]=$c[2-$l[$_]] ;$g[23-$z][$x+($_?1:-1)]=$l[2+$_]>1?'-':$c[2];$g[24-$z-($l[2+$_]>1?1: 0)][$x+($_?2:-2)]=$c[$l[2+$_]>1?1:2]}},z=>sub{$z},x=>sub{$x},n=>sub{$ n=pop},c=>sub{$h=0;$e=2;$k=pop;$q=0;if(!r(7)){splice@f,$n,1;$$_{n}($h ++)for@f;}}}}1..$j;while(1){exit if@f==1;for$m(@f){$$m{i}();$$m{d}()} my@n;for$a(1..25){push@n,join'',"$/|",@{$g[$a]},'|';@{$g[$a]}=map{' ' }0..$=}print$/x$=,@n;select$c,$c,$c,.2}
Loved the obfu. Good job! Wading through the maps and logic was quite a challenge. Especially the outtermost map, with a hashtable of subs inside.... ugg, what a mess! That's not a bad thing, in the context of a fantastic obfu. Keep it up!
