Yeah, that didn't take long. The Blackberry Storm has an application where you can make different lightsabers appear on your screen. When you move the Storm, the accelerometer (a motion-sensing device) makes the lightsaber sound effect and vibrates in your hand. Depending on how and where you move the Storm, it will produce different sounds. It works best when I plug my computer speakers into the headphone jack.
I knew it wouldn't take long before I found the most useful application of my new phone!
