How do I decorate my small attic bedroom with a chimney in the middle of the room?

My family just moved into a new house on a lake & I moved into the attic, with sloped ceilings and all. I love this type of room except I have this big red brick chimney coming through the center of the room because of the fireplace downstairs. How do I decorate my room (and/or the chimney) to make it look cool & not totally out of place in my bedroom?
