I received an email from playbill that was about the Roundabout Theatre Company's production of Sunday in the Park with George. They are running a great marketing campaign revolving around pointillism and connecting the dots, blending the marketing campaign and the show in an unique way that I think is a great idea.
You can check out the campaign at: http://sundaydots.com/
You don't need to buy tickets or contribute money to join in the fun. They ask for a name, email, and 5 things you like to do on Sunday. You then get a dot which is part of the overly picture.
And while I am a fan of the show, seeing George Seurat's original work "Sunday Afternoon on the Island of La Grand Jatte" at the Chicago Art Institute is a great experience as well.
