Dow: Giant Chalkboard

Monday (9/19), at the corner of Broome and Crosby in SoHo, Manhattan, 90,000 people walked by a giant chalkboard (46 ft tall) with only a twitter handle (@giantchalkboard) and website (giantchalkboard.com). Yesterday, began an unveiling of an elaborate equation full of challenging twists and turns that combines mathematics with numbers that are significant to scientific human achievements throughout history - and a banner that says 'Solutionism. The new optimism'. People are invited to participate and guess through twitter and the website and on the 5th day the answer will be revealed. This mathematical poem and social media effort is the teaser to a new campaign from Dow, from Draftfcb Chicago.
