  //plus transparency for effects

  ellipseMode(CENTER);

  for (var i = 0; i < 10; i++) { // draw ellipse 10 times, each time 
    //rotate by 36 degrees to create flower

For my wallpaper project, I was inspired by my current design studio poster project which involves many flower illustrations. I found this wallpaper project to be a fun extension of Assignment B, as I extracted the element of nested for loops and combined it with the usage of ellipse rotations in order to personalize the drawing. This project was a thorough learning experience, as it allowed me to apply newly learned topics into my own projects.
