I can't think of anything specific but v interested. I recently saw a picture of a pirate theme party wheere they carved a pirate ship out of a water melon and then filled it with balls of melon and it was in a sea of grapes, looked fantastic. Maybe you could do something along those lines for a centre piece. Obviously not a pirate ship but maybe a skull or something....
