I made some pie slices with GD. Then animated them at different intervals with Javascript.
You can test your browsers timing by watching these as they should line up frequently.

Create the images.

use warnings;
use strict;
use GD;


my $slice = 1;
my $start = -90;
my $end = -84;

while ( $slice <= 60 ) {

    my $image = new GD::Image(64,64) || die "couldn't create image!";

    my $white = $image->colorAllocate(255,255,255);
    my $black = $image->colorAllocate(0,0,0);
    my $red      = $image->colorAllocate(255,0,0);
    my $blue  = $image->colorAllocate(0,0,255);



    my $file = "slice$slice.png";

    open( FH, ">", $file ) or die "couldn't open $file\n$!";
    binmode FH;
    select FH;
    print $image->png;
    close FH;
    select STDOUT;
    $slice++; $end += 6;

Download ← Creates 60 slices.
Download ← Creates 24 slices.

Here's the code to animate. I won't print it out here because a lot of it is taken verbatim from the book "Javascript The Definitive Guide". A very good book that's always on hand when I'm writing Javascript.


and the HTML.
