Austria Solar, a solar energy association, has printed its annual report on light sensitive paper. When indoors the paper appears to be blank.As soon as it is exposed to sunlight facts and figures start to appear. It is a fantastic way to align the nature of the business with a document that is usually more practical than creative. Although we're sure that the company has produced another version of the annual report for those who want to focus on the figures, this video certainly has viral potential. Highlighting the power of the sun in a creative, well-designed and unique way.
