Creative Confidence- thirty circles challenge

In a video Tom Kelly has his audience partake in a thirty circles challenge. In the book, creative confidence it comes ups as a creative challenge that can be done in three minutes or less and alone or in a group. I decided to take about a minute and see what I could come up with drawing thirty circles. These sketches aren't pretty - it's about getting comfortable with iterating multiple ideas regardless of it being unpolished. I did two rounds of one minuet Andy results are in the photo. I'm curious to know what you could come up with - be it variations or unique ideas. Take a page and fill it with thirty circles and see what types of things you can think of to draw in or with the circle. Mine is below !
