How about a language learning subscription? There are many websites that offer online language courses that are interactive and engaging, like Babbel or Duolingo. This gift will not only provide your girlfriend with a fun and productive hobby, but it will also give her the gift of learning a new skill. Another idea is to buy her a beginner's language book, an audio book or a language CD set with a guidebook to study together. Or you could even plan a trip to a country that speaks the language she is learning, so she can practice what she has learned in real life!
Or you can get her a star map with the date of your anniversary.
