Lightsaber Unleashed

"Ever wished you could swing your iPhone around like a lightsaber?"

This questions is the start of the description of Lightsaber Unleashed - a must-have application for every geek.

You enable/disable your lightsaber by clicking on the lightsaber, while your iPhone emits sound effects from your phone's speaker. When you swing around your the sound effect's too. It's very funny and for free!

So, I'm looking for someone to duel!
