Hmm... lost a post... anyway, sql not an option since sql won't have access to the required offset... However, I think I've solved it with localtime(+$x) and then extracting the time part... Thanks all...

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?$d=8:_}1..50;print$c}0..59;print$/}0..20
