generally this would be done in an image editing application like Photoshop,
Expression Design, etc.
you'd do your layers then compile it into a single image, slice it up if
you're going to tile it, etc.
you may be able to get a similar effect using nested divs (layers) each with
a different background image, but your images would have to be transparent
where actual color/ shape wouldn't exist (a transparent background for each
layer's background image) so you'd have to use a .gif or transparent .png
file (you may run into cross browser issues with the .png).
If you could explain what you're trying to do with a little more depth it'll
help get you a better answer.
