(Artist Sketch) In this exercise, I combined my code from example 1.1.3 with Courtney Spisak's code from example 1.1.2. My code creates the grid of ellipses and the grid of squares. Courtney's code creates the moving square and the background changing color. I combined the code so that the my grid of ellipses gets drawn behind the square from Courtney's code, and then my grid of squares gets drawn in front of everything. In my code, I practiced using nested for loops to create the grid of ellipses and another set of nested for loops to create the grid of squares.
