The mission stencil story is an interactive, choose-your-own-adventure story that takes place on the sidewalks of the Mission district in San Francisco. It is told in a new medium of storytelling that uses spraypainted stencils connected to each other by arrows. The streetscape is used as sort of an illustration to accompany each piece of text. —Sidewalk stencil choose-your-own-adventure (Flickr)
