The first solution (Chris) first defines a function that takes a pure function and makes it wiggle, then goes on to draw the graphic elements of the plot (axes, legend, the curve). This way everything is still a fully symbolic graphic object and can be exported as pdf. The second solution (Simon wood) uses rasterzation and image processing to do the trick, thus losing vector data.
