Tired of the boring white look of your Gmail inbox?
Why not change its theme?
I don't know exactly how long it's been around, but yeah, Gmail actually offers several cool themes to spice up your mailing experience. There's Beach, Phantasea, Ninja -- heck, there's even a Candy theme.
How to do it?
Just click on the Settings tab on the upper right hand corner of the Gmail window. Click on Themes, which is the last tab. Then choose your new skin.
