Crackberry.com member dmglakewood developed a neat lightsaber app for the BlackBerry Storm, that allows you to swipe the screen for different colors of the Jedi weapon.
After choosing your appropriate “laser flavor”, you’ll just have to swing the handset left or right in order to hear the sound of a “real” lightsaber.
The app is still in development, so there are a few bugs to work out, but you can find more info on that original piece of software and a download link on the Storm Lightsaber App thread.
