How about something like tickets to an experimental theater performance or art exhibit? You could also get her a book on avant-garde movements or experimental artists. If she enjoys creating her own art, you could put together a kit of art supplies that are off the beaten path and encourage her to explore new techniques and mediums. Another idea is to find a unique piece of jewelry or clothing with an unconventional design that fits her personal style.
Or you can get her a star map with an important date you share.
