Image display apparatus comprising two or more arrays of light sources is described. Each array is rotatable around a common axis, and the light sources in each array are arranged so that each light source traverses along a unique path around the common axis. A controller is adapted to modulate the intensity of light emitted by each light source as it traverses its respective unique path such that the light sources in combination cause a desired image to be visible to an observer by virtue of persistence of vision.
