This is a Pong clock for your Android phone. It tells the time by playing Pong against itself.

Sander Muller came up first with the idea to have a Pong Clock. A really great idea and a fantastic device. Then lately Lady Ada designed a wonderful hackable clock platform, called MONOCHRON. The first implementation on the platform was, of course, a Pong Clock.

As I received my new Android phone, a Motorola Milestone, I was looking for a simple project to get my hands dirty. So what could be more obvious than writing a Pong Clock.

If you want to take a look at the source, check out my PongTime repo at github. The code is not pretty as can be, mostly because of optimizations to get rid of object creation and thus garbage collection.

If you are reading this with your Android phone, you can grab the Pong Time app directly in the Android Market. Otherwise search for “Pong Time”.
