I found these mazes on Twitter and thought they might make a relaxing puzzle interlude. They come from photographs of the street in front of the Museum of Mathematics (MoMath) in New York. The idea is to traverse the mazes from the Start to the Goal making only right turns. It was difficult working out the pattern of the green maze, especially the upper right corner.
