Haystacks is the title of a 25 oil on canvas series of paintings by Claude Monet. He started in the summer of 1890 and continued through the following spring. It is known for showing differences in perception of light across various times of day, seasons and types of weather. I just thought it was cool that he could do 25 paintings and have them look like the same scene just with different colorings and things like that. Also, the subject is bland but it they still look beautiful.
