The Gmail blog has a post up right now that’s interesting for a few reasons. First, it was posted around midnight of a Friday (this is supposed to be my no-news quiet time, Google). Second, it’s written as a chat exchange between two Google employees. And third, it has a kick-ass new Nintendo-esque theme.
Themes allow you to customize the look and feel of your Gmail account. To choose a theme, click a thumbnail on the Themes tab of your Gmail Settings page.
