A new Kickstarter campaign promises the best of both worlds for Star Wars role play weapons. The lightsaber is made of foam that’s designed to take abuse without breaking or disintegrating. Calimacil has developed its own motion sensing and sound effect hardware to give your swings and hits realistic sounds. The most expensive version offers smartphone connectivity and color-changing blades so you can customize your saber exactly how you want it. The Plasma model will cost you $500, and give you all the features and the most detailed lightsaber handle.”]
