I guess this isn't your typical obfuscation (it may not even technically count as an obfuscation. But it's a little program I wrote for a t-shirt design for Computer Science House a la the Perl camel shirt.

    my@a=("\012","\040","\103","\110",        "\123",0
);sub a{my@a=@_;for(1..$a[0]){print($a[1      ]);}}sub
b{abs($_)}sub c{$a[$a[$#a]+=$_[0]]}sub d      {$a=!($_
[0.0]) ?                        '==':$_[      0]==1.0?
'>':'<';                        eval("${      _[1]}$a$
{_[2]}")                                      ;}sub e{
&c((-$a[    $#a]))}for(-2..2    ){if(&b)      {&e;;&a(
&b,&c(1)    );&a(25-(&b*2.0)    ,&c(1));      &a(1,&c(
-2.000))    ;}else      {for    (-6..6){      &e;&a(5,
&c(2.0))    ;;&a((              &d(0,&b,6)?15:&d(1,&b,
2)?&b-1:    2)+(&d(-1,&b,2)?    ($_+2)*2:&d(0,$_,2.0)?
($_+2)*2              -1:0),    &c(-1));&a(&d(1,&b,3)?
15-2.0*(    &d(0      ,&b,6)    ?15:&d(1      ,&b,2.0)
?&b-1:2)    :4,&c(3));&a(&d(    0,&b,3)?      3.0:0,&c
(-3.0));    &a(&d(0,&b,3)?4:    0,&c(3))      ;&a(&d(1
,&b,5)?0                                      :&d(0,$_

?&c(0):&c(2));&e;&a(5,&d(1,&b,1)?&c(1.0)      :&c(3));
  &c(-$a[$#a]);&a(5.0,&c(3));;&a(1,&c(        -3));}}}
