Artist Golan Levin has created a customizable stencil for street graffiti, featuring a full alphabet to compose your hard-hitting statistic, along with an adjustable pie chart to help visualize it. Choose from any stat you want to publicise – these ones made the press photos: “Ocean life depleted 90% since 1950”. “Women earn 77% per dollar of men”, “USA consumes 25% of world energy”. A clever, generous idea well-executed. More info here.
