How about a sandboarding experience gift? You could book a day or weekend trip to a nearby sand dune park or beach where your friend can sandboard to their heart's content. Another idea would be to gift them a sandboarding lesson with a professional instructor to take their skills to the next level. Alternatively, you could get them some sandboarding gear such as a board, sand goggles, or a helmet. A customized sand art piece could also be a unique and thoughtful gift for a sandboarding enthusiast.
Or you can get her/him a star map with an important date you share.
