I found a enlightening yet brief conference Alexia López gave on the Big Ring discovery: https://youtu.be/fwRJGaIcX6A?t=173 https://youtu.be/fwRJGaIcX6A?t=173 Here's an in-depth seminar on the findings of the Giant Arc in the Sky, her work prior to the Big Ring discovery: https://www.youtube.com/watch?v=-zkGk6EPMC8 https://www.youtube.com/watch?v=-zkGk6EPMC8 She was also featured in a pop-sci BBC Four documentary: https://www.youtube.com/watch?v=S36MqEzUzIw https://www.youtube.com/watch?v=S36MqEzUzIw Unfortunately all videos are of quite bad quality, but the explanations are a good introduction to the work.

That last video, at about 3:55, shows the ring as a bunch of red balls surrounded by a bunch of blue balls. All the balls seem randomly distributed, but a small subset are colored red. I wonder what makes those balls different? There doesn't seem to be anything unusual about their arrangement, other than they chose to color them red.
