Not sure if anyone else is aware but if you use Google as much as I do I found that there is a Doodle Theme you can apply to your iGoogle page and it's so clever and cute. You have to see it because it's hard to describe but essentially it is just the hair on top of a doodle's head and it's the same color and texture of my doodle and it makes me smile every time I see it.
If you go to iGoogle.com you can make iGoogle your homepage or just customize it so whenever you go to iGoogle you can see you personalized view of your theme (doodle) and any parts that you add like weather, news, email etc. Once you are at igoogle.com you should see a place to set a theme for your igoogle page and then just search doodle and you'll select it and it will be applied to your page. Hope that helps.
