Microsoft’s Excel is the preferred tool of teachers, CPAs and other pencil pushers out in the world, but who would have thunk that it could also potentially be used to create stop motion animation?

He and his team of musicians shot and filmed a performance against a greenscreen and then proceeded to recreate it using Open Office and Excel by hand. We’re not sure how much patience is required to pull this thing off, but we’re pretty sure it was all worth it. Catch a video of his performance below.
