This special face is the simplest, even the easiest of all, you just need to create the structure, ie the eyes, face, with ellipses, and create an arc to make the mouth, then if we want to touch up the color , we would do it with fill (0,0,0); To make the whole face move we just have to substitute the ellipses and the arc for the X mouse that would be the horizontal axis, and the mouseY that would be the vertical axis .Example:ellipse(mouseX, mouseY, 400, 400);
