I liked working on this project because I gained a better understanding of how extensively you can use math in P5. I discovered how to make the flames by accident by randomizing one of the values in the equation of the curve. Once this happened, I was able to come up with a concept for the rest of the project. I liked working with colors and the mouseIsPressed conditional to change the image from red fire to blue fire. In the future, I would like to have a better ability to implement the map() function, as I feel that it would have been useful for my goals in this project.
