Frank Lloyd Wright (FLW) an American Architect has been an influence of mine since I saw his work as a young man living in the Chicago land area. His home for the early part of his career is located in Oak Park Illinois; below you can see the basic shapes that make up an elegant room.
Part of unlocking peoples ability to be creative is leading them to unlocking it slowly, simply, through small creative accomplishments. Looking at the image above it appears elegant and rich, but when it is broken down, it is quite simply block and tube shapes. Simple elegance is one of those things FLW achieved so well.
