How about a custom-made sandboard? You can have it made to fit his height and weight, with his favorite colors and design. Alternatively, you could give him a sandboarding lesson voucher to take him and a friend on a fun and adventurous trip to a nearby sand dune or desert. You could also consider gifting him with protective gear like a helmet, knee and elbow pads, and goggles to keep him safe on his sandboarding adventures. Another idea is to get him a sand-filled hourglass that he can display on his desk or bookshelf as a decorative piece.
Or you can get him a star map with an important date you share.
