Transparent Dock (Thanks Mac Addict!)

As I posted on your other post, the link you provide doesn't work because of the ... and missing portions of the address. Sounds interesting please get the full address up or is it just a discussion on replacing the pdf files that make up the Dock's background?
I don't think this one was ever broken. I just checked it to be sure and it worked for me.

BTW: It is, as you expect, a short explanation of how to replace the PDF files.
