Here is a little mod that may be phoney baloney, so we'll let you decide.
Most phones now have a camera and can run Java, there is no reason that some software couldn't be written to watch for movement in the camera, and translate that into mouse signals for the PC. Bluetooth could be used to send the data to the PC. So there was the challenge, a java program that took multiple frames from the nokia camera, translated that into direction and speed and sent it to the PC as mouse movements.
I'm not much of a software/programming junkie, but I know there are a lot of you out there that are. Some people are calling this mod BS, some people are saying legit. Anyone out there have some insight whether this is possible or not? Hit up email@example.com for a comments invite and let us know.
