Today Google is launching a directory of iGoogle themes, comprised of all different design of themes that iGoogle users can add to their Google personalized home pages. In the meantime, Google also announced the release of a set of application programming interfaces (APIs) that developers can use to develop themes for this iGoogle. To make it easier for users to add theme, Google has prepared an “Add it now” button below each theme that you like, click on any one of the buttons and the design will instantly appear on the page. There are 18 themes in total at this moment, and many of those themes are developed by Google, only few of them are from the third-party developers.
