The GlowPadView library is basically Android's Lock Ring (way of screen-unlocking and alarm dismissing), but extended and targeted to Honeycomb and later versions of Android. I tried getting it to run on Gingerbread, but even NineOldAndroids (http://nineoldandroids.com/) didn't give me everything I needed.
