I usually do one Google Hangout a day, sometimes more (I also use the same kind of Beam robot that Snowden uses.) I work out of the guest bedroom in my house, and I've never been happy that other people can see the bed behind me. I recently bought a WebAround ($(removed) on Amazon, which is a big round screen that attaches to my chair, and creates a neutral wall behind me. I wish I'd bought it a long time ago.
It's easy to fold up:
I wish it were a bit larger, because the edges show unless I'm pretty close to the computer. But it is so much better than not having it.
