Paper and collage art has always been one of my favorite mediums. Either sculptural or two dimensional works, I think it is the art form most similar to graphic design. Louis Reith the Amsterdam artist repurposes out book cuttings, maps and other old sheets of paper into amazing little pieces. The map pyramids are by far my favorite, but I also really like the abstract pieces, which have some interesting textures and compositions. Head over his site to check out more of his work.
