Something my brother did with unused skate decks was make wall lights. You could probably do the same with the snowboard if you'll like looking at it- you get the art of the board and light.
He used an ikea multi-colored led light strip (like these: Ikea lights
) and either glued or screwed them to the top of the boards, and has the bottom graphics pointed out (so top of decks and lights towards the wall). Then got about a 2" spacer for between the board and the wall that the screws will go through, some long screws, and put it into the wall through the truck holes. You could drill through a few of the inserts for the same effect.
I don't think I have a pic, but it looks pretty sweet.
EDIT: I don't have any pics, but I'll try to get some.
