Bubble Cloud: Projection of an Image onto a Bubble Cluster

We introduce Bubble Cloud ---a technology that uses a bubble cluster for displaying images onto a screen. Bubble Cloud projects images onto bubbles without confining a fog and can float in the air by changing an operating condition of the bubble cluster such as altering the size of the bubble. Moreover, the user can modify the display because its shape is composed of clusters. A floating bubble cluster can be controlled and adjusted by hand in arbitrary directions by electrifying the bubble cluster.
