Little Fafnir is a baby dragon that lives in your live wallpaper. it is somewhat cute... If you don't do anything the little dragon falls asleep. If you tap him a few times he feels happy. Wallpaper "time" changes according to time of day. etc. etc.
However, it seem to take a long time to initialize, and use a lot of memory. Not sure if it's completely worth it.
