Someone asked how to review the poll questions after a class. One way is to slog through the video replay of the class. Another way is to take a screen shot of the poll questions window during the live presentation to save/review later. Depending on the real estate and the number of questions, you may be able to capture all the questions in one screen shot. On a MacBook, you take screenshots by running the ScreenShot app. I'm sure there's a way to do that on PCs and Linux systems. Alternatively, you could just take a picture of the presentation on a smart phone.

In Monday's class, Eryn showed an exercise drawing random circles with random colors. They showed the example one way, and then with the Style[] function. When Eryn did the Style example, they ran out of time. The final step is easy: you just wrap the second expression with Graphics[]. I just did this in a notebook and attached it here. Hopefully, that will display when I post this message.
