Dunno about real applications using this neat app developed by Alex Winston, but it’s here anyways:

Wolfenstein 3D using two devices, one as a screen, the other one as a virtual joystick that uses the accelerometer to control the character.

All good… except Alex, maybe next time you’ll want to blow your nose before recording the video? *yuck*

Hope you recover from your flu though! 😛
