I've been tweaking this for about a month. I wanted something unadorned: easy to look at and easy to use. This has something of a retro/command line feel to it. I mostly selected apps for the Today screen that don't have keyboard shortcuts - again, just trying to make things as easy and convenient as possible.
I've learned as much as I want to about the GIMP for the moment, so all application icons are stock Dimension Zen icons. I messed with pretty much everything else, though. I was very happy with my emulation of the network activity icons, inspired by the vodafone today theme.
I've set this with a pure black wallpaper for maximum visibility. I've found a few other grey-striped walls that work really well, too. They're attached.
Zip file only, for now. I've tested this on a T-Mobile 8800 running 4.2.1.x. I have no idea how it will perform on other devices, and make no warranties about its operation on anything. Make sure you choose the correct version for your device and OS below.
