Frank Lloyd Wright’s homes have some beautiful features, but they’re not always practical. In this vertical fireplace at Wingspread, the logs burned at the bottom, causing the long pieces of unburnt wood to collapse into the room. From that point on, the fireplace was strictly for show.  (Lori Rackl / Chicago Tribune)
