Christine spotted the link to Firda's new & improved "Firdamatic: the Design Tool for the Uninspired Webloggers".
You can use this wizard to create your own two & three column css layouts. It's really very cool. Here's a sample blog using the two column Firdamatic. There's some other great designs that Firda has created at Book of Styles.
While we're on the topic of templates, designs, and layouts for bloggers, go check out Neil's new XHTML valid "fade" template, courtesy of Donna. You can see it in action on Neil's blog. If only I weren't so lazy I might even roll that sucker in here. Very nice, Neil.
