This makes me unbelievably happy!
Sidewalk stencil choose-your-own-adventure
Some stencil artists created a Choose-Your-Own-Adventure game using spraypainted sidewalk stencils: players start from one of two jumping off points and walk aroudn the neighborhood, making choices and following directions. It's a love story, and if players do it right, then end up meeting.

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.
Its a love story with 2 characters who start in different locations. His story starts at 16th and Valencia, in front of the Crown Hotel / Limon Restaurant with the text "He Leaves his Lonely Apartment." Her story starts at 21st and Guerrero in front of a stunning mansion with the text, "She Leaves her Lonely Apartment." Eventually their paths merge, at the point where they meet, and their paths travel together until drama pulls them apart.
