web design - circles

I am wondering if there is a way to arrange the information on a page using the circular shape and have it be still legible and easy to navigate as most normal websites are. We have been learning about the grid, and while I understand that concept and that its important to use it in order to organize information, I just wonder if we could use a circular system and still achieve the same results. Since the computer screen and the window on the screen acts as a framing device for the website this is probably part of why rectangular and square shapes work well in website design. But in my graphic design classes at UH, I also learned that it is sometimes interesting to break the rectangular framing device with circles. I think it would certainly be eye catching, but I'm not sure if i could organize it well enough for the audience to understand it and for it to be intuitive. I have tried looking for some examples of using circles to organize information on the web but haven't really come up with anything. If you know of any examples, please let me know.
