How about getting him a tattoo kit so he can practice and learn more about tattoo artistry? Alternatively, you could get him a book or subscription to a magazine that features tattoo designs and artists. Another idea is to buy him a custom-made temporary tattoo set, so he can design and create his own tattoos without the commitment of permanent ink. You could also look into local tattoo expos or conventions that he might be interested in attending.
Or you can get him a star map with the date when he was born.
