A transverse axis fluid turbine with controllable display components thereof is disclosed. The turbine has a base structure, rotor rotatably attached to the base structure and at least three blades rotatably attached to the rotor. A matrix array of light reflective or emitting elements is mounted on the flat blade surface. The light reflective or emitting elements are controlled by a control unit in such a way that the light reflecting or emitting provides stable still or moving image(s) to its viewer(s) while the turbine is in operation.
