Abstract
Abstract A non-alphanumeric, video image modifying device for television pictures which is easily attachable to a wide variety of typical televisions. Said modification of the picture image consists of real time reduction of picture data into abstract motion and color. Said device maximizes diffused light transmitted through its translucent screen by reflecting light emitted from the cathode ray tube off of the highly reflective surface of a lattice located between the cathode ray tube and said translucent screen.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
154 words
A real-time video image modifying device said modification being the hundredfold reduction of video resolution relative to the source television and said device comprising: a molded plastic housing said housing having an open forward end and an open back end; a flexible hanger strap attached to the top of said housing and arranged to allow said device to be hung in front of the screen of a television; a flat translucent but not transparent screen mounted in said housing and arranged to diffuse light through said forward end opening; a deep lattice formed from slats having highly reflective surfaces, said slats being spaced apart a distance greater then several pixels, said lattice being mounted behind said translucent screen inside of said housing and interlocked with said housing; a flexible collar surrounding the periphery of said lattice and said collar held between said lattice and said housing when said lattice is glued into said housing.
Claim 2
Dependent Claim
154 words
A real-time video image modifying device said modification being the hundredfold reduction of video resolution relative to the source television and said device comprising: a molded plastic housing said housing having an open forward end and an open back end; a flexible hanger strap attached to the top of said housing and arranged to allow said device to be hung in front of the screen of a television; a flat translucent but not transparent screen mounted in said housing and arranged to diffuse light through said forward end opening; a deep lattice formed from slats having highly reflective surfaces, said slats being spaced apart a distance greater then several pixels, said lattice being mounted behind said translucent screen inside of said housing and interlocked with said housing; a flexible collar surrounding the periphery of said lattice and said collar held between said lattice and said housing when said lattice is glued into said housing.
Claim 3
Dependent Claim
24 words
The device of claim 1 wherein the collar consists of a low density flexible foam, such as urethane, which has several inches of flexibility.
Claim 4
Dependent Claim
45 words
The device of claim 1 wherein said lattice has less than 100 openings which are squares 3/4 inches to 2 inches on each side and are at least 5/8 inches in depth and the walls of said lattice being less than 3/16 inch in thickness.
Claim 5
Dependent Claim
17 words
The device of claim 1 wherein the grid lines of said lattice are oriented vertically and horizontally.
Claim 6
Dependent Claim
