Control Your PS3 With a Nokia N900

It may not display the output from your PS3, but it does replace the controller and requires no modding skills. Instead you just need a copy of the BlueMaemo Bluetooth emulator. With the emulator you can trick the PS3 into thinking an N900 is a controller and then use the touchscreen to handle input.

Kind of a neat little trick but i'm not sure it would actually be worth using during controlling a game.

What would be good is a way to use PS3 controller for your phone, especially for something say an iphone.
