Until approximately three weeks ago, I'd never used Zoom. Now it's a regular part of many of our lives. You could just continue to have your boring wall or messy house in the background, but a few C-U institutions have compiled some local background options that you can use. Follow the links to find all of your options.

I didn't know how to make these a Zoom background, and maybe you don't either, so I Googled it for you.
