How about getting tickets to a live theater show for your wife and you to go see together? You could try to find a show that you think she'll especially enjoy or that you've heard her mention before. You could also consider making it a special evening by planning a nice dinner beforehand or a romantic walk afterwards to talk about the show. Another idea would be to get her a backstage tour of a theater or tickets to a playwriting course or acting workshop. These ideas can help her experience the theater in a deeper, more personal way.
Or you can get her a star map with the date of your anniversary.
