Need To Create The Circle As Part Of The Array

This code here is the product of one of our tutorials on arrays...

http://www.openprocessing.org/sketch/76844

What I need to do is figure out a way to recreate that code in a way that allows me to create another ball, which is atually integrated in the array. Instead of the current method of a similar circle appearing when and where the mouse is clicked and then continuing to follow the mouse... I want the ball to be created where the mouse is clicked and then for it to stay where it is as a seperate, newly created entity, such as the falling blocks.

Someone tell me where I'm going wrong????
