Incidentally, Field's image on the first link is a strange attractor rather than an IFS. It's an Icon, which is one of the few equation to produce symmetrical sets. The degree of symmetry is one of the equation constants, so I'm sure he won't have any trouble creating a new image for each of his wife's birthday.
