Abstract: The present invention is an aerodynamic wind riding antenna ornament comprising a main body adapted to be rotatably and slidably attached to an antenna mast. The main body has an aerodynamic lifting surface to harness airflow from the movement of a vehicle to move the ornament up and down the antenna mast. The main body also has an aperture of sufficient size to allow for the device to freely slide up and down an antenna mast. Retaining means is removably coupled to the aerodynamic lifting surface near the aperture to prevent the aerodynamic wind riding antenna ornament from sliding off the top of the antenna. The retaining means can comprise a snap-on clip, spring-like clip, or a portion of an ornamental figure removably coupled to the main body. Optional stopper clamps can be removably coupled to the antenna to restrict where the device travels on the antenna. The device can have optically perceived indicia to increase the appearance.

Abstract: Considering the latest vehicle anti-theft systems and anti-theft warning systems that abound today, the theft of vehicles has not been slowed down to any appreciable amount. In fact, the car theft industry lids virtually kept pace with the car manufacturing industry. This invention has taken a common sense and practical approach to an anti-vehicle theft system that renders the front windshield opaque when the ignition switch is turned on and the vehicle is attempted to be stolen, while the security control switch is placed in the "on" mode. One embodiment was a thermopane type windshield with a space between two plates of unbreakable glass. The space between the two plates of glass has an opaque curtain or blind pulled up inside the void space from the bottom of the windshield to the top of the windshield to render the entire windshield opaque. Another embodiment is to provide several optional features that may be purchased by persons with limited funds although these options are not really required.

Abstract: A display device for automobiles and other vehicles alternately displays two different messages in an interesting manner calculated to attract attention. The device comprises an outer case having a plurality of spaced windows and, mounted within the case, a slide having a plurality of spaced indicia spelling out the two messages. Windows and indicia are positioned in such a manner that upon relative movement of slide and case, produced by inertial, centrifugal or gravitational forces generated by the vehicle movement, the slide alternates between two positions within the case, thereby alternately spelling out the two messages.
