RELATED APPLICATIONS 
     This is a continuation-in-part of U.S. patent application Ser. No. 11/098,962 having a filing date of Apr. 5, 2005 now abandoned and which claims priority off U.S. Provisional Patent No. 60/560,366 filed on Apr. 8, 2004, both of which are incorporated by reference as if fully rewritten herein. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to a rotating camera attachment and, more particularly, to a rotatable lens system that works in conjunction with after-market digital and video cameras by means of a corresponding electronic device. 
     2. Description of the Related Art 
     Special events have been captured ever since film-based cameras were introduced to the market nearly 100 years ago. The recent advent of digital cameras and digital camcorders enhances a person&#39;s ability to easily and inexpensively capture events in more striking detail. One disadvantage to this technology is that a person is only able to partially capture a moment based on a very limited field of view typical of most cameras. A standard camera affords its viewer only a 90° field of view while a wide-angled camera can approach a 150° field at best. 
     The limited fields adequately allow a viewer to record a particular object within view, but they prevent the viewer from simultaneously recording the events that occur around and the ones that react to the primary object. Accordingly, there is a long-felt need for a means to capture and to simultaneously display a primary object and the supporting objects in the periphery and the background. A means that accomplishes the dual-recordings in an easy and an effective manner will provide later viewers a stronger impression of an event captured with even greater accuracy. 
     The present invention provides such a means. A search of the prior art revealed no patents that read on the claims of the present invention; however the following references were related:

     SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a means for an event or an object to be captured while the background objects or the supporting objects surrounding the primary object are simultaneously captured. It is an object that a dual-lens camera or camcorder accomplishes the foregoing object, wherein the first lens is a wide-angled lens that captures a primary object in a manner similar to that well known in the camera arts. A second, rotating lens captures the events surrounding the primary object so that a viewer receives a greater impression. 
     It is an object that the second lens is rotatable 360° so that images can be captured simultaneously to the front and to the rear of a camera, e.g., a parent may capture his or her child hitting a home run while simultaneously capturing the crowds reaction, a person can capture a bride&#39;s and a groom&#39;s first dance while simultaneously capturing the guests celebration, etc. 
     It is an object that the images captured in both lenses are shown by means of a dual-split screen or a picture-in-picture screen display. Therefore, the present invention provides a means for a camera to act as two cameras that combine to display images on one screen. 
     It is a further object of the present invention that the second lens is a rotatable lens that is adapted to attach to after-market cameras so that a person may easily secure it to an existing camera and convert it to a dual-lens recording system at the times he or she desires. It is an object that the present invention is not so obtrusive, complex or expensive that it makes it an unattractive means to capture a special event. 
     It is a final object of the present invention to provide all of the advantages the foregoing objects entail.
