Remember the announced new Star Wars sequel, I can't blame you if you don't but just in case, I have embedded below the trailer.
If you watched the trailer, you might notice the new lightsaber, no, I am not talking about the new swiss army like qualities, I am talking about that "flickery" texture that the lights have. Star Wars nerds from all over the world have come up for explanations for this. Some say it has to do with the crystals or something, but I don't really understand, due to the fact that I have a life. Well search no more! The answer was that Jony Ive, the designer of products such as the iPad, iPhone, and The MacBook line of computers, met JJ Abrams, the director of Star Trek and the latest star wars movie, and suggested that the look would look cool.
