Well here is a simple way to put it into a Tk marquee.

UPDATESet timer to update every 5 minutes.

#click on marquee to remove 
use strict;
use LWP::Simple;
use Tk;

my $text;
my $mw = tkinit;
$mw->geometry('+20+20');
$mw->overrideredirect(1);
my $label = $mw->Label(
                  -textvariable=>\$text,
                  -font=>'courier',
                  -bg=>'green',
                  -bd=>4,
                  -relief=>'ridge'
                      )->pack(-fill=>'both');

getnews();
$mw->repeat(300000,\&getnews);

$label->bind('<ButtonRelease>',sub{$mw->destroy});
$mw->repeat(160,[sub{$text=~s/(.)(.*)/$2$1/;}]);
