After Google's personalized homepage , Orkut themes, now Google has launched the Gmail Themes. This kind of service is already avilable in Yahoo mail- Being a good competitor, Google took this step and tried to give their users, a beautiful interference.

                               

According to google blog "We wanted to go beyond simple color customization, so out of the 30 odd themes we're launching today, there's a shiny theme with chrome styling, another one that turns your inbox into a retro notepad, nature themes that change scenery over time, weather driven themes that can rain on your mailbox, and fun characters to keep you in good company," 

Gmail's help center provides an interesting tidbit about the new themes: "In some cases, you can also customize by location. Some themes change during the day, and we use the location information you provide to correctly time these changes with your local sunrise, sunset, and/or weather. If you select one of these themes, you'll see a Country/Region drop-down menu appear."
