I was a little inspired by the post-expressionism art period and Van Gogh’s paintings and his swirling brush strokes to create this portrait. I think the most difficult part of this project was setting up the variables. Overall I really enjoyed working on this; I wanted to set up a for() loop to create the 10 spirals but in the end I was unsuccessful although I am still thoroughly proud of my work.
