Quote:
"Joyce Wieland, the wife of Michael Snow, has used loop printing for at least two kinds of structure. In Sailboat the loop gives an illusion of continuous movement as a boat sails from screen left and out of screen right repeatedly; in 1933 a single shot of a street taken from a high window with people rushing in fast motion and slowing down to normal motion (without a change of shots) is seen about a dozen times. Occasionally the title, 1933, is printed over the entire shot, and between each set of repetitions there is white leader marked by different red flashes."
