There's an all new LED controller on Kickstarter that creates music synchronized lightshows automatically and operates entirely on it'sown. It plugs directly into WS2812B LED strips and uses audio from a 3.5mm port from line-in or a mic. It's great for making all kinds of custom light installations.
