Generated images, where each pixel is a cell in a grid maze, colored by its distance from the start, normalized against the longest distance in the maze. Each maze is generated with a randomized depth-first search, a very simple maze generation algorithm.
I wrote this as a Processing sketch, and rendered the image iteratively as it was generated. It was mesmerizing. Then I had it generate lots of images, and eventually even printed a book of them. I've since lost the code, but managed to hang on to a number of the generated images, which you can browse here. There is a striking variety in the compositions that emerge from the simple, generative process.
