How about a new kiteboarding harness or board for your grandpa? Another idea could be a kiteboarding lesson with a professional instructor to improve his skills or learn new tricks. You could also get him a personalized kite or a kite-making kit if he has an interest in DIY projects. Finally, you could consider giving him a kiteboarding trip to a place he's been wanting to visit where he can enjoy kiteboarding in new and exciting surroundings.
Or you can get him a star map with the date when he was born.
