The bubble screen uses air and water as a display medium.
The screen is a tank of water and the pixels are individual air bubbles that are released from a mechanism at the base. This enables the screen to display characters typed on the computer to which it is connected. As the bubbles rise, the message floats upwards and disperses on the surface.
The size of the pixel buttons can be controlled, and this affects the speed at which the bubbles rise, as well as the intensity of the font.
The effect of the fleeting floating display is soothing and relaxing as each pixel bubble ascends smoothly in time with its peers. This could easily be modified by lighting to achieve different effects, and the whole mechanism could be scaled up to create complex and spectacular displays.
The movie exhibited at the MoMA's Design and the Elastic Mind exhibition shows a prototype bubble screen in action.
