We all have already seen these kind of photographs whith car lights and stars drawing psychedelic lines or with water looking like milk, due to the long exposure times. What is less popular, it's the next level of long exposure. The yellow lines in the above photograph are the result of our sun, brushing the sky during this 1-year long exposure shot by photographer Michael Chrisman with a pinhole camera. A solargraphy.
If you want to shot your own solargraphy, this guide explains pretty well the necessary steps.
Michael Wesely is also an adept of very long exposures. In fact, spanning during 3 years, his work show the renovation of the MoMA in New York city.

These static timelapsesare not only mesmerezing, they're a touching tribute to the first photograph ever made (below) in a time when long exposure was a necessity.
