This really cool image was made by someone calling themselves ‘Mr. Mallon’ and records the path of the sun through the sky over a period of six months. The image (actually a negative) was made by leaving a pinhole camera (instructions to make your own here) set up in his backyard for six months. Each line traces the path of the sun on a different day and the breaks in the lines are periods where it was too cloudy to get much sun. Looks like Mr. Mallon had a few pretty dreary weeks.
