Ten in ten nerds allways wanted to have a Lightsaber, the sword used by the Jedi knights from Georges Lucas creation: Star Wars. There’s a lot of models and versions in different sizes, sounds and colors of Luke Skywalker‘s and Darth Vader‘s swords, but this iPhone app is lightweight, easy and very nice.
Lightsaber Unleashed is a free teaser for the game The Force Unleashed. It emulates the sounds of the “real” Lightsaber, using the iPhone built-in accelerometer when you move the phone like a sword in the air (“air sword”). You can choose one of five game characters: Darth Vader, Rahm Kota, Maris Brood, The Aprentice e Shaak Ti, or create a new one using an existing photo or taking a new shot with the camera, when you can also choose the laser color of your sword.
The background music from the game is also available, when you and your nerdy friend start to “fight” with your iPhonesabers. Ideal to kill some time at the office (when your boss is not around) or to animate that Star Wars Party. Well, you can allways trick some Trekker, but the risk is all yours
