Gmail themes are now available
Google integrated the ability to change the appearance of the interface (the so-called topic) into the Gmail mail service. More than 30 themes are available today (many of them are familiar from iGoogle). To enable theme support, go to the “Themes” tab in the “Settings” menu (in the “Settings” menu, “Themes” tab, if you have an interface in English). Over the next 2 days, topic support will be available for all accounts.
