jwz's Dali Clock: Android
To get back into android development I've decided to port the somewhat mesmerising Dali Clock to android. The original was coded by Jamie Zawinsky (jwz).
It is implemented both as a daydream and a normal app. It's not (yet?) available on the play store, but you can download the source and apk here: http://www.jwz.org/xdaliclock
