Roogle uses Plone template/CSS
I noticed right away that the site uses the Plone look and CSS design. Take a look for yourself. He gave credit to other people he "stole" things from (as he put it) or was inspired by, I think it would have been nice for him to give attribution for the design of the site.
On his personal weblog he says "Whole new look and feel (that's the "Less Google", about page, contact info, incremental database index in progress for some of the updates and the absolute fastest webmastering I've ever done."
It's a feather in Alexander Limi's hat that his CSS and design were so easily reusable.
