   I was trying to have the circles bounce back down from the top, but I couldn't grasp how 
   to do that from the class notes.

I meant to ask this last week, but I don't think I fully grasped how to have an object bounce off the frame and move back again. We did it in class going horizontally and I tried to transfer that to happen vertically, but I couldn't get it to work.

Hi Greta. You're very very close to figuring this out, so I'm going to point you to this section of the Week 4 class notes. I recommend that you carefully read through these two bits of pseudocode, the code snippet that comes next, and the accompanying explanation.

In that example, I was talking about horizontal movement, so I was using the words "left" and "right". But you are talking about vertical movement, so wherever I say "right", you could think about the bottom of the draw window, and wherever I say "left", you could think about the top of the draw window.

Try reading through that, pay attention to the code in blue, and see if you can make a similar addition to your code.

Great work so far!
