IOCountDown is a project mainly written in Java, it's free.
Google IO 2011 Countdown Clock
Semi-clone of the Google I/O 2011 countdown clock. It was created using the Andengine 2D physics engine. I hacked this out in 24 hours for the Google Android Last call contest. Then sadly I submitted it at 5AM, the email bounced and woke up past the deadline. Oh well, so is life. Hopefully this code can be useful to someone. Enjoy ;-)
