Heh - probably OS specific (Win2k for me).

I get JUST ANOTHER PERL HACKER (but you probably guessed that ;)

map{$a=1-$_/10;map{$d=$a;$e=$b=$_/20-2;map{($d,$e)=(2*$d*$e+$a,$e**
2-$d**2+$b);$c=$d**2+$e**2>4?_:0}1..99;print$c}0..59;print$/}0..20;

For some wierd reason, even though perl reimplements half of the c library, it uses the library random generator even on systems where it's not really good. This has the consequence that you can't rely on rand returning more than four random digits and also that random numbers are highly platform dependent.
