One my most recent trip to Ikea, my dad and I spotted this neat wire cable that you hang pictures from. Its made up of a long cable, two end caps that screw into your walls, and multiple hooks that you clip your pictures into and suspend them from the cable. I think it is a modern, sleek way of displaying photographs, greeting cards, or even could be used as an inspiration "board". I hung mine over the long side of my bed. I love how the images you put up can quickly be replaced simply by unclipping them.
