"And then there’s HD rumble, a concept that uses vibration technology to simulate a new type of force feedback. In one demo, I was shocked how well it conveyed the feeling of spheres sliding around inside of a mystery box. As I tilted the controller back and forth, I could feel the contents rolling up and down in the palm of my hands."

Now this has me excited.
