Here's a potentially silly question.
When I navigate to https://hangouts.google.com/
in Chrome, it shows me a panel of my friends and a lovely image harvested from Google+: a lighthouse, or a waterfall. While these are very nice images, I'd love to be able to customize what shows up in the background. A web search doesn't yield up much, and the forums are full of people trying to change their backgrounds on Android...
Has anyone tried to do this? Is there a setting I'm missing? Help, nerdy backgrounds would make the new Hangouts just about perfect!
