So this is pretty awesome: A recent rising star in the Japanese pop music scene is actually nonexistent in any way we "normals" would consider an individual to exist. She is, in fact, a hologram named Hatsune Miku. Miku is the product of a software craze sweeping Japan right now called Vocaloid. You type in whatever lyrics you want and pick some notes from the program, and hit play and what you've wrought is sung by the program. There's no need for you to open your mouth.
