Translucent Concrete Lets The Light Shine In

Get ready for windows that never break with translucent concrete. A German design firm has created load-bearing concrete containing optical fibers, allowing light and color to pass through to the other side (the shadowy hand is what you can see through the concrete in direct light). The result is that you can live… » 1/07/08 12:00pm 1/07/08 12:00pm
