This was my final project in CS176B - Intro to Networking 2. The project was split into two parts, 1) a mobile phone application running on Android or Windows Phone 7 that connected to a game server for a geo-caching game; and 2) the server, of course. I picked the server and developed it to run on Google App Engine, using a framework called Tipfy. There is an instance running at cs176b.appspot.com, though it is less interesting without a the mobile client. (psst! if you put "/admin" at the end of the url you can get into the administration interface without a password...)
