We describe a novel display concept where levitating particles are used to add a dynamic display element to static physical objects. The particles are actuated using ultrasound, for expressive output without mechanical constraints. We explore novel ways of using particles to add dynamic output to other objects, for new interactive experiences. We also discuss the practical challenges of combining these. This work shows how the unique capabilities of levitation can create novel displays by enhancing another form of media.
