I remember the first time I saw a Mark Rothko piece at the Art Institute in Chicago. I’d only seen reproductions until that point, and I never understood why people considered the late painter so important. Anyone can paint like that, I thought. But sitting there in front of those blurry fields of color, I felt suddenly overwhelmed. I didn’t completely understand what I was feeling, but I finally realized why Rothko is considered to be one of the most important artists of the 20th century. It was a revelation. This video about flying cats affected me in exactly the same way.
