We present a table tennis game concept, implemented for Symbian OS/Series 60 mobile phones, using the phone's integrated camera as the main game controller. The game demonstrates how the integrated cameras are already usable for interaction on mobile phones, with real time performance. Data communication between the phones is handled using Bluetooth, but the implementation would allow for using slower radio links too.
