Play with numbers

[Anonymous Monk]

An script I wrote, which outputs Japh. It decrypts $x by multiplying 2 integers and the act like it is a binary number. The code isn't really exciting, but the way I encoded 'Japh' is kinda interesting.

$x = '3336703366667337000033670003'
     ;$d=sub {chr unpack('N',pack (
     'B32',substr(('0'x32).((shift)
     * (shift)),-32) )) ;};print ${
     dx( $d, $x) }; sub dx{ while (
     $_[1]=~/(\d{6})(\d{1})/g){$out
     .= &{ $_[0]}($1 ,$2); }\$out;}
