ABSTRACT:
A system and method of producing an image using a plurality of independent pixel devices, each of which includes one or more light emitting or polarizing elements. The pixel devices are fixed (e.g. on the side of a building) or are moving (e.g. on water or falling in air) within an image space in which an image is to be formed. A controller determines, based upon the locations of the pixel devices within the image space, what portion of the image each pixel device is to reproduce, and then commands the pixel devices to use the emitting devices to reproduce the corresponding portion of the image. As the pixel devices move, the new locations of the pixel devices are mapped onto the image, and the control of the pixel devices is modified accordingly so that the image produced by the pixel devices is not distorted by their movement.
