Close of Business is a new video series that we're trying out. The idea is simple: at 5 p.m. (or thereabouts), we post a quick video summarizing the top three news stories of the day. Some of them we'll have written about; others will just be what people were talking about on the Internet.

Today, I also show you a little bit about the way we make art for the Technology Channel.
