A few weeks ago following the announcement of the Nexus 4, a Jellybean system dump was leaked with a variety of great apps that were backwards-compatible with other devices running 4.0+, and even some lower OS versions. One of those was the new Clock, which I found to be a great improvement on the previous versions (again, Google taking on more Cyanogen ideas but I digress).
Themed Android 4.2 DeskClock - XDA thread with download links
I started a thread on XDA with a variety of themed Clock apps for everyone to enjoy. You can find over 25 different styles I created, along with some requested by others. Since starting the thread, Jellybean 4.2 was added to AOSP, and I found that the AOSP version of the APK had some new changes. So I just completed a total rebuild of every themed version I've made so far, using the new APK as a base. This could cause some problems for people who are not yet on 4.2: I am still running a 4.1.2 build, and I was greeted with an error message when trying to add the new digital clock widget option. Everything else seemed to work fine in my daily usage (alarms, countdown timer, etc).
