At Dupont Lightstone we produce a new screen technology which is based on concrete and fiber optics. Its a ground-breaking new type of digital signage that puts an interactive image directly on surfaces like floors, sidewalks or other exposed surfaces like facades at street level. By embedding optical fibers into the concrete and controlling the position of each of the fibers the image is projected through to the other side where it appears. Thousands of tiny light emitting fiber ends comprises the live image and the same fibers detect touching of the surface which makes the Lightstone interactive. Its vandalism and weather proof signage It can be used as a floor that you can walk across Its aesthetic signage that becomes a natural part of the buildings architecture. It has the power to surprise because the viewer doesn’t know that its a screen until a live image appears out of nowhere. The Lightstone is mainly used for showing information, advertising or graphic light effects both indoors and outdoors. Lightstone screens in floors, facades and even pavements make live signage in places like hotels, airports, night clubs, shopping malls and in traffic a lot more interesting and applicable. Dupont Lightstone welcomes you to the digital stone age.
A video explaining just how good BT infinity is compared to what I had before. I hopefully this video gives some good advice to people wanting to switch over to BT infinity.

FIBER WAVE rustles with the wind and glows with the energy of the sun. It is environmental art which needs no energy. One can feel the wind, but cannot see it. It is when we see the movement of something that we become aware of the wind. FIBER WAVE is just such a device for making the invisible wind visible.

Optical Fiber and Copper Cable and The Differences
Article by Vivek Gupta
With the advancement of technology, there have been numerous inventions and discoveries. The latest one has been that of Fiber optic cables, which have gained more prominence in the market than the copper cables. These cables are widely used in offices or residential areas. Read the write up ahead to know the differences between optical fiber and copper cable:
About Copper Cable and Optical Fiber Copper cables transmit information through electrical signals. It has been used as a speaker system wire, telephone wire, computer cable wire etc for over years now. Optical fiber comprises of plastic or glass strands to transmit data or information digitally with the use of light rather than electricity. On the other hand, copper cable encompasses of a single thread of copper. The size of the cable varies depends upon its purpose. Sometimes, the cables are protected with the help of a covering known as braiding. The difference between copper cable and fiber optic lies here as the latter cannot transmit electricity but known for providing high theoretical performance.
Difference between Copper Cable and Optical FiberThe significant difference between copper cable and optical fiber is their different resistance against interface. Copper cable is fairly weak against signal interface that comes from microwave or cell phones. With use of fiber optic cable, you are free from all these problems. Moreover, copper cables are inexpensive and suitable for all your home requirements. Fiber optic cables can transmit information to long distances and more swiftly than the copper cables. Moreover, this cable has less weight and a smaller diameter making it much better than its counterpart.
Furthermore, these fiber optic cables require less power and are inflammable. Copper cables can be electromagnetically tapped whereas optical fibers are not easy to be tapped without interruption in the signal. Optical fiber cables help in multi-channel transmission though the use of a single line. Therefore, this cable finds wide application in wiring of home theatre systems and is too expensive than copper cabling.
But the added benefit of using the fiber optical cables are that they offer higher bandwidth and are easy to be installed than copper cables. Fiber optical cables have the capacity to carry signals such as millions of megabits or terabits per second as compared to copper cables, which can carry 2.5 megabit per second. Also, fiber optic cables offers security and less attenuation rate but requires minimal maintenance. LANs( Local area network) also use fiber optics in the backbone and copper cables for the desktop.

Short excerpt. I put together a system to control leds lighting the fiber optics in this relief map model. Southern Custom Exhibits built the model for the US Army Corps of Engineers. The animation works great. Sorry the video does not, LED multiplexing causes beat frequency issues with video scan. Better than nothing.
