You're all awesome (especially clarknova, in this case) for getting started on the K2 hackin'.
If anyone's feeling a little meta, I whipped this up for ya.
I didn't spend too much time on the image itself, but now have a pixel-perfect template in Photoshop for replicating the stock screen saver look. If anyone wants an image Kindlefied (I'm not going to attempt to replicate the etching effect) or if you want the PSD, drop me a PM. Caecilia LT Std (the font) is required.
