Artist Stefan Löffelhardt of Germany does some particularly interesting things with materials and space. Some of the images when in thumbnail size look like landscapes, or seascapes. But blown up they are actually photographs of colored plastics side by side. Other pieces hang and he also includes structural elements made of wood, foil and a multitude of other nice materials.
I originally saw the work at Contemporary Art Daily, which I have added to my links. I recommend going back through their archives.
