Where is codex in GW hompage?

I'm just a noob on the block, but any pictures of the said GKT? They're design is of high caliber and epitomizes pure baroque galantry, none can possibly compare. How could you improve or change that which is revered to be the Emporers finest? I'm just saying it better not look like a smoldering steaming bag of hot manure. Just rephrasing my last statement, I don't wish to be disappointed.
