Red and Green Tape

Haxton staples down the center line between two sheets of white paper that are rolled on the floor vertically so that the entire frame is white. He takes a roll of red masking tape and, beginning at the bottom, makes three lines from the center of the frame to the right, one behind the other. Haxton pulls a roll of black paper down over the right half of the frame, over the red lines. There is a cut to negative. He rolls white paper down the right side, and puts red tape in the same configuration as before.
