Great obfu. Funky!

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

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!

    ++ for pointing out that select can be used this way; I had thought it had to do with filehandles, and had not realised this use for it.

    As for the rest of your improvements... well, I'll have to look at those when I have more time.

    update: I've looked at them now, and they all seem pretty straightforward; you just did a more thorough job of golfing than I.
