Try to replace the main loop with the following: 

use Time::HiRes "sleep";
use List::Util qw"min max";
for (0 .. 19) {
    print "\n" x 4;
    my $r = sub { 1 + int(min(rand($_[0]), rand($_[0]-1))) };
    my($m, $n) = (&$r(7), &$r(7));
    my $p = rand(2*pie);
    for my $_c (1 .. 100) {
        liss $m, $n, $p;
        sleep 0.03;
        $p += 0.4 / (3 + max($m, $n));
    }
    sleep 0.5;
}
