in thread Lights out puzzle

I changed the definition of the show and toggle methods like this:

sub show { my $board = shift; print "\e[H"; for my $row (@$board) { return unless defined $row; print map $_ ? '*' : defined $_ ? '.' : '', @$row; print "\e[K\n"; } print "\e[J"; use Time::HiRes "sleep"; sleep(6e-3); } # show sub toggle { my ($board, $x, $y) = @_; my $old = $board->[$y][$x]; return unless defined $old; $board->[$y][$x] = $old eq 1 ? 0 : 1; } # toggle
and now I can see the lights being chased down to the bottom of the board. Looks nice.

    Yes, in fact, I did something similar for debugging :-)
