This sketch is still a work in progress. I think I managed to grasp the basics of loops and repetitions but as I tried making a more complicated thing I got turned around a little and I'm not sure at this point what was intentional as opposed to a happy accident. I will sit longer this week and try to make the ellipses move or draw in steps or something. But for the purposes of the class I'm somewhat happy with the end result.
