About

“Not all who wander are lost.” - J. R. R. Tolkien

Wander the actual streets of San Francisco, Brooklyn and Barcelona as puzzle mazes! At Dirt Alley Design, artist Michelle Chandra transforms city street grids into a fun, interactive art print where you have to find your way to famous destinations such as San Francisco's Twin Peaks or Coney Island in Brooklyn!

The inspiration for creating puzzle mazes out of city street grids came when Michelle watched Mike Bostock's Visualizing Algorithms talk on maze generating algorithms at the 2014 Eyeo Festival. 

A (Very) Short History of Mazes


The first mazes were labyrinths created 4,000 years ago. In medieval manuscripts, a labyrinth was oftentimes used to symbolize a city. Puzzle mazes were first created as garden hedge mazes in England such as the Hampton Court Maze. Since these early beginnings, puzzle mazes have been built around the world from maize, hay, stone and wood! 

Designing a City Maze Art Print

Michelle creates each puzzle maze art print design by hand using the underlying street grid as the foundation. She begins the design process by downloading city street centerline data available in the public domain. Streets are removed and intersections modified to create paths you can get lost in.

Carving a maze design from a city grid, and drawing each road segment for the final design by hand, means a puzzle maze art print can take many hours of work to create. When a city maze art print is near completion, Michelle tests the city maze design with friends and family to make sure the puzzle maze is, well, puzzling!

The final posters are screen printed by hand on French Paper Co paper to create a unique art print made entirely in the USA.
