Google has released an iGoogle Themes API, giving designers the ability to create their own iGoogle Theme. With the iGoogle Themes API, developers can design and share a theme with the tens of millions of iGoogle users around the world, providing even more options for users to customize their iGoogle experience. To jumpstart the development, and for the a little bit of inspiration, Google has also released custom themes from innovative designers Yves Behar, Mark Frauenfelder, Troy Lee and John Maeda. A new themes directory, similar to the Google Gadgets directory, has also been created.
