This assignment asks you to create a bouncing smiley face screen saver using Dynamic HTML. The script below uses two variables, x_motion and y_motion, to keep track of the horizontal and vertical directions in which the smiley face is moving. These variables will either hold the value "plus" or "minus". A "plus" value calls for a number to be added to the current position. If the variable is x_motion, adding a value will move the smiley face to the right. If the variable is y_motion, adding a value will move the smiley face down.
