I used the rose formula from Wikipedia. I think this project is very fun because it is not super hard but simple code creates a crazy result. This project also allowed me to understand “constraint” and “map” better. I never thought that they can be used together, and they are so cool! I do not have enough time to render my drawing, but it turned out fine after all. I enjoy this project a lot.
