Patent Images
1. Apparatus for projecting an adjustable pattern of light spots on interior surfaces of a substantially conventional room, so that the interior surfaces can be painted with spots of paint at the location of said light spots, said apparatus comprising:
- a light source;
a container surrounding said light source, said container having a substantially vertical central axis and being perforated with apertures such that when said container is placed within the room, light from said light source passes through said apertures and creates a pattern of light spots on the interior surfaces of the room, said apertures being arranged such that said pattern of light spots resembles an arrangement of stars in a known stellar constellation;
means for adjustably positioning said light source within said container to alter said pattern of light spots; and
a stand supporting said container and having a plurality of legs of independently adjustable length such that said container can be tilted to adjustable position said pattern of light spots on the interior surfaces of the room,wherein said light source comprises a light bulb having a filament of length short enough so that said apertures are substantially as wide in shortest dimension as said filament length.

Abstract
A system for painting images of stars and other objects on the interior surfaces of a room with phosphorescent paint utilizes a projector to project symbols on the surface to indicate locations of points to be painted. The projector is adjustable to accomodate rooim size and position of the viewer.

2. A method for simulating the appearance of a night sky in a room, the method comprising the steps of:
-
projecting a first pattern of light spots on an interior surface of said room, said first pattern substantially resembling from at least one point of view in said room a simulation of the night sky; and painting said interior surface of said room with spots of paint at locations where said light spots are projected. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)

10. A method for simulating the appearance of a night sky in a darkened room, the method comprising the steps of:
-
perforating a container with apertures; mounting a light source inside said container; placing said container in said darkened room such that light from said light source passes through said apertures and projects a pattern of light spots on an interior surface of said room, said pattern substantially resembling from at least one point of view in said darkened room a simulation of the night sky; painting said interior surface of said room with spots of paint at locations where said light spots are projected; and blinking the light source off and on during the painting step to determine at which of the light spots the spots of paint have been previously applied to the surface and at which other of the light spots no spots of paint have yet been applied, said paint comprising a material that glows in the dark after the light source turns off.
