Gmail themes?! How do I change my Gmail theme?

It was only a day or two ago that I learned that Google had unleashed themes in Gmail, actually. Prior to that, there were third-party add-ons you could download and install that would give you some control over the Gmail look and feel (mostly color schemes) but truth be told I've always been nervous about the possibility of a UI hack messing up the functionality of the system.

The good news is that Google's now added about twenty themes of its own, ranging from the banal with just the slightest tiny changes from the standard (now "classic") design to those that are quite amazingly different and really quite fun.

Here's how ya get there...

When you're logged in to your Gmail account, look on the top right for "Settings":

Click on "Settings", and you'll see the usual set of tabs, with something new on the far right:

Chose Themes and you'll be amazed at the number of cool themes that are now available for Gmail users:

Finally, I suspect that the woman you were spying on, uh, whose computer you glanced at, was running the "ninja" theme, but the one I like is actually called "desktop":

Nice. And great job, Google, with these new Gmail themes!
