As I was thinking about what I could do this project on, I realized that I could use the noise line that is used in the plant the flags project as an object or representation of a dragons body. I would just have to upload an image of a dragon head to make it look realistic. As I was thinking about how the project was going to look like, I kept remembering the movie, Spirited Away and how Haku kind of moved like a wavy line. I decided to use the movie as an inspiration. I tried to add rectangles going by to represent the scales coming off of the dragon but I had a hard time focusing the scales around the body so I just left them as wind strokes.
