I learned that the background on the Dock in Leopard is a set of 4 PNG image files, and I got the hamsters running. I made Sky and Wood for you, and here’s what they look like:


Installation
To ‘install’ them, go to /System/Library/CoreServices/Dock and click on the gear icon in the Finder window.
Select “Show Package Contents” and then go to Contents/Resources/ and copy these files in. They will replace the system images, so be sure to backup the originals!
