The Java piece is a couple of ghosts that float around, following the mouse around the
screen. The figures are white on a black screen. The ghost on the right moves slightly faster than
the one on the left and her mouth closes when you click the mouse then opens up again once you
click the mouse again. The ghost on the left blinks as the mouse is held down.
The piece is composed of several ellipses that form the bodies, arms, eyes, and mouths of
the ghosts and rectangles form the teeth and the right ghost’s open mouth. The “float” phrase
establishes that the position of the mouse will affect the position of object with “x” and “y” in
their coordinates. The “mousePressed” phrase allows the left ghost’s eyes to stay closed as the
mouse is held down. The “int” phrase which creates the variable titled “variable” allows for the
part of the right ghost’s mouth to stay closed and open, alternating with every mouse click. For
both of these, the features are given the appearance of being closed by switching color from
black to white.
