Updated for the 20120418 official nightly...and zipaligned this time :P
SystemUI.apk - It adds a new set of battery icons with a little keyboard. I assume that is for when you have an external keyboard attached.
Trebuchet.apk (NEW) - Orange theme added for homescreens and appdrawer. It also replaces the blue architecture wallpaper with an orangified version. It's pretty hideous though. :) I'll try to come up with something better at some point.
framework-res.apk - Now available and hopefully working too. I've never had any success copy/pasting framework-res. I always have to use adb.
