You could make a frame for it with sections, and could fix the frame to a coffee table top, then close it in with glass, great when its done. I spent a full weekend doing a picture with pasta/rice/lentils and coins for a design assignment for college, it looks brilliant hanging up. You could go with a picture as well, if you wanted another interesting talking piece.
