A device for the generation of two-dimensional and three-dimensional virtual
color
patterns by the single or multidirectional rotation of a movable body containing
light emitters of differing colors. The light emitters may be intermittently or
continuously flashed by a wind-powered alternating current generator that also
serves as a bearing for rotation. In the preferred embodiments, wind reactive blades
take the form of various horizontal or vertical shaft windmills with slender or
broad blades.
