German communications agency Serviceplan and graphic designers Matthäus Frost and Mathias Nösel have devised a uniquely appropriate way to present an annual report. The client is Austria Solar, an association of 51 solar energy companies. When examined indoors, the pages of the document are so stylishly minimal as to be entirely blank.

However, when exposed to sunlight, the paper lights up to reveal a clear and business-like three-colour graphic presentation. Since its founding in 1999, Austria Solar has lobbied hard to expand solar energy provision. This unusual corporate report should certainly attract attention to that cause.
