34. Create a grid of objects with nested while loops

We have seen in previous episodes how to create many objects at once using a while loop. This time we use a while loop inside a while loop to create a grid of objects. The result is a collection of objects (rectangles or circles in our example) distributed in the screen in a pattern similar to the white and black rectangles in a chess game.
Using a loop inside a loop is something very common in programming, and we will see more examples in coming episodes.
