Creativity and resourcefulness is smart and attractive. When used well even looked-down upon materials can be a part of inexpensive solutions. These cinder block set-ups look good, work well, and are modular. They can easily be taken apart to make something else, they can be easily moved, or they can be altered to grow or shrink with changing needs. Anyone can pay for a piece of furniture but if you have the smarts and the touch of style to make simple solutions look good, you should rock it!
