Logo (June 3, 1983-August 15, 1984)
Visuals: On a black background, there is a group of pink and blue horizontal lines crossing over each other; the pink lines move upward, while the blue lines move downward. Then the groups of lines (in box-like shapes) pull away from each other towards both corners of the screen, with the pink line-square moving towards the top left corner and the blue line-square moving towards the bottom right corner. The two squares (which are slanted by this time) are still joined to each other, with the bottom right corner of the pink square joined to the top left corner of the blue square. As the two shapes move to opposite sides of the screen, the left side of the blue square crosses over the right side of the pink square. When the two shapes cross each other, vertical lines form from the opposite end of each shape and nearly connect to each other, forming an S-like shape. After the S is formed, two groups of lines travel from opposite corners of the screen, with the blue lines travelling from the bottom left corner and the pink lines travelling from the top right corner. The two groups of lines connect to the S, forming a hexagon. As the "S hexagon" shines, it moves backwards. When the "S hexagon" is in place right above the center of the screen, the words "SHERWOOD PRODUCTIONS, INC." appear underneath in a thin futuristic font.

Trivia: The logo was created by Rod Dyer Design.
