Hanging up old wakeboards in the Den suggestions?

So Ive finally made myself a "guy room" in my new pad. Hooked it up with a big screen TV, sound system, PS3 the works.

I wanted to decorate the walls with some of my old boards, since they are just collecting dust and taking up space in storage. Anybody done this and how did they do it? Id like to avoid drilling holes in the board but I still want to hang it up nicely on the wall somehow.
