“General Kenobi. Years ago you served my father in the Clone Wars. Now he begs you to help him in his struggle against the Empire. I regret that I am unable to convey my father’s request to you in person, but my ship has fallen under attack, and I’m afraid my mission to bring you to Alderaan has failed. I have placed information vital to the survival of the Rebellion into the memory systems of this R2 unit. My father will know how to retrieve it. You must see this droid safely delivered to him on Alderaan. This is our most desperate hour. Help me, Obi-Wan Kenobi. You’re my only hope.” -Princess Leia, in Star Wars: A New Hope

Of all the dreams that the imaginative galaxy far, far away where Star Wars take place has spawned in our collective imagination, none is more sought-after than the dream to have our own light saber. While neural technology and bluetooth connectivity might soon give rise to a force-like reality, I want to focus on what’s a reality today.
