A billboard for the mathematicians of the world.
A 46 foot long chalkboard and two live painters formed the new campaign for Dow. The painters created an elaborate equation on the giant chalkboard, and the only clue as to what it all meant was a banner hanging from the bottom of the billboard saying, “Solutionism. The new optimism. Dow.”
People were invited to guess portions of the equation by submitting their ideas through the website and by tweeting at @giantchalkboard. After 5 days the answer to the equation was revealed to be 7 billion, which represents the soon-to-be world population.
