A while ago I talked about creating an iGoogle theme. I've had it up and running for a little while so I thought I'd let other people know how they can use it if they'd like.
First you have to have an iGoogle page, which if you have a Blogger you've already got (you just might need to set it up.) Then you you just have to go to:
That will automatically apply my theme to your iGoogle page with your settings. The screen grab is of my personal page at mid-day. The drawing and colors will change depending on the time of day, and I completed three additional drawings for morning, evening, and night which you can see if you use this theme (and sit at your computer all day.)
