I was toying with Pattern Finding problem posted by artist and came up with a solution that I thought might make an interesting obfu. Read that thread to what its supposed to do (especially the updated rules)
use integer;$"="|";$\="\n";$S='Just Another Happy Perl Hacker';$C=5;$L += length($S);%0=();sub o{$l=shift;return 1 if(exists($0{"@$l"}));$0{"@$l +" }++;@n=0..$#$l;for$i(@n){for(@n){next if$i==$_;return 1 if index($$l[$ +i ],$$l[$_])!=-1}}0}@1=map{$_*length($S)/$C}0..$C-1;$.=0;while($.++<$L*1 +00 ){@0=();for(0..$C-1){my$str=($_==$C-1)?substr($S,$1[$_]):substr($S,$1[ +$_ ],$1[$_+1]-$1[$_]);push@0,$str;}$.=0,print"@0" unless(o(\@0));$;=rand( +@1 -1)+1;$1[$;]+=(rand(3)>1)?-1:1;$1[$;]=0 if$1[$;]<0;$1[$;]=$L-1 if$1[$; +] >=$L;$1[$;]=$1[$;-1]+1 if$;>0&&$1[$;]<=$1[$;-1];$1[$;]=$1[$;+1]-1 if$; +< $C-2&&$1[$;]>=$1[$;+1];}

[marioroy]: Yes. I've been working on MCE and MCE::Shared. These are completed and released. MCE 1.830 and MCE::Shared 1.831. Saw the LWP::Simple and P::FM thread and thought to help out.
