Report For Solar Power Company Can Only Be Read Under Sunlight [Video]
A sun-powered report presents the yearly figures in a unique and humorous way.
Ad agency Serviceplan has created a clever way to present their client's (a solar power company) annual report. Each page of Austria Solar's 2011 annual report is blank and the contents of the page is only revealed when it's being read in direct sunlight. The report that's “powered by the sun” is fitting for a solar energy company.
The brochure was printed using photochromism ink, which reacts under sunlight. See this idea in action by watching the video below:
