Abstract: Advertising in the sky is produced by a plurality of fog emitting nozzles, for example each at the outlet of a canister containing fog producing material under pressure, which canisters are supported in spaced apart relation along a length of a winch line cable suspended from an aircraft. Each nozzle is controlled by a solenoid valve, the solenoid of which is activated on a timed schedule predetermined to contribute to the production of one or more letters, numerals, and/or designs in the sky in the creation of advertising material.

Abstract: A multiplicity of optic fibers are secured at their outer ends in a spaced-apart pattern at the front surface of a viewing panel and at their inner ends in a concentrated, spaced-apart pattern at the rear, input surface of a reader panel for registry with correspondingly spaced holes arranged in an elongated tape in patterns of letters, numbers and/or other desired indicia to be displayed for viewing in greatly enlarged form. A source of light is positioned on the side of the tape opposite the inner ends of the optic fibers for illuminating those fibers which register with holes in the tape. Drive mechanism is provided for moving the tape past the inner ends of the optic fibers for producing a traveling light display.
