For this design, I decided to look at the story from the narrator's POV, which is why I have chosen a bit of a psychedelic design.
According to the book, the narrator Chief Bromden suffers from paranoia and hallucinations, because of which his objectivity is somewhat compromised. The black hole at the end of the tunnel represents a fog that the narrator often refers to, it symbolizes a lack of insight and escape from reality.
I have used the same grid throughout the project, but in this design, I have chosen to break the grid since this design is inspired by the nature of the narrator, and from the eyes of the narrator.
