A friend of mine wrote this and it's still kind of a work in progress as you can see stuff commented out but this is what he's got so far. Requires the font below.

<?php
$rand = rand(1, 100000);

$file = "$rand.logo.gif";
$font = "lokicola.ttf";

if ( $_GET )
{
$w = $_GET[w];
$h = $_GET[h];
$f = $_GET[f]; # number of frames
$size = $_GET[size];

$delay = $_GET[del];

if ($f < 1)
{ $move = 0;
   $f = 1;
}
else
{ $move = $w/$f; }

# new imagick object
$img = new Imagick();

# remove NULL's from colors
foreach ($_GET[c] as $temp )
{
  if ( strlen($temp) > 0 )
   { $colors[] = $temp; }
}

# how many colors?
$n = count($colors);
# make gradients till next to last color
for ($x=0; $x<$n-1; $x++)
{
   $next = $x+1;
   $gradient = "gradient:$colors[$x]-$colors[$next]";
   $img->newPseudoImage( 100, 100, "$gradient" );
}
# loop last color back to first color
$last = $n-1;
$gradient = "gradient:$colors[$last]-$colors[0]";
$img->newPseudoImage( 100, 100, "$gradient" );

# go back to top of stack and append
$img->resetIterator();
$bar =  $img->appendImages(true);

# rotate & resize
$bar->rotateImage(new ImagickPixel(), 270);
# $bar->scaleimage($w, $h, FALSE ); 

# new object for frames

for ($x=0; $x<$f; $x++)
{
# roll, resize and add to frames
$bar->rollimage( $move, 0 );
$bar->scaleimage($w, $h, FALSE ); 
$frames->addimage($bar);
$frames->setImageDelay("$delay");
}

Woah - that script is amazing!

Thanks for sharing it with us!

That script is written as a form so you can try many different variations.

btw, this is the Imagick portion of my friend's site showing some really good examples of what can be done with the Imagick Class.
