Look for anything that resembles the letter "I" (capital i) in your environment.
Document what you find as images, sketches, videos, words or any combination of these.
Examples: Steel I-beams in buildings, or the use of the letter "I" in Edward‘s Munch‘s paintings.
Where did I go? To the Icelandic landscape in the south-east, where I partly grew up as a child, close to Keflavik, where the landscape is kind of flat and it would not be unusual to find fences made from “rekaviður" – drift wood found on the shores.
