Gmail users utilizing the web interface who would like to give their interface a new look each day should play around with the Themes available in the settings. While this is not a new feature of Gmail, applying a theme other than one of the simple “color only” ones usually changes quite regularly.
For example, I am currently using the Planets theme which changes the top banner daily. My wife uses the Bus Stop theme which changes with the local weather (rain, snow, sunny, etc.). Additionally, you can use the Random theme to get a fresh look anytime.
While the variations are not drastic (unless you use Random), they change enough to keep the monotony of having the same old theme away (assuming you get board with predictability).
