Have a break, take some time to have a look at the site below:

Maybe depressing but just click on this breathing earth site and see!!
An absolutely amazing thought-provoking site! (....start placing your cursor on the various countries and catch the stats!!!)

Don't know about the technology involved and/or the accuracy of the data input - but it sure is interesting!

Might make a good screen saver or desktop...

Solar Powered Video Screen - XXL

Video walls are now part of many major cities - used for advertising, information and, sometimes, art. Beijing is about to officially switch on what is thought to be the world’s largest.

Located on the entire side of the Xicui Entertainment Complex building in Beijing, China, ready for the Olympics, the GreenPix-Zero Energy Media Wall is made up of energy efficient LEDs, can show 2,292 individual colours and is equivalent to a monitor screen covering 24,000 square feet.

The entire screen is solar powered using photovoltaic panels built directly into the structure. During the day they collect energy, which is stored ready for powering the screen at night. The wall was designed by architects Simone Giostra & Partners, New York, with the lighting design and facade engineered by Arup in London and Beijing.

The building will open to the public this month, with a specially commissioned program of video installations and live performances by artists from China, Europe and the US.
