Abstract: A built structure having an upward facing surface having a first image positioned thereon. The first image is visible from craft passing overhead and revenue is derived from the image on the upward facing image. The image is an active image that is controlled by a local controller so that the image can be replaced by a fresh image from a remote computer that communicates with the local controller via the internet.

Abstract: A built structure having an upward facing surface; the built structure supporting a first image and a second image; the upward facing surface overlaid by the first image in the form of indicia; the first image arranged for visibility from overflying craft; and wherein revenue is derived from the upward facing surface; and wherein the revenue is a function of a cone of legibility; the cone describing an inverted conical section of a sphere whose generator is equal to the distance of resolution of the smallest discrete detail of the image; the second image in the form of a substantially vertically oriented sign having second indicia thereon adapted for viewing from ground level and for which separate signage rights can be negotiated; the upwardly facing surface mechanically associated with both the first image and the second image.

Abstract: A system for the application of an image to an upper surface of a built structure, the image arranged for visibility from over-flying craft. An upper surface of a built structure incorporating indicia thereon or therein; the indicia constructed so as to be discernable by observers in craft passing over the built structure when the craft is within a predetermined legibility distance of the built structure.
