How about a walking tour of street art in your city? Many cities have street art tours where you can learn about and see some of the best pieces in various neighborhoods. You could also consider getting him a coffee table book of famous street artists or purchasing a limited edition print from one of his favorite artists to hang in his home. Another idea could be to surprise him with a private graffiti lesson or workshop, where he can learn some of the techniques and create his own piece of street art.
Or you can get him a star map with the date when he was born.
