You have to check out this site.
It's pretty dern cool what our eyes tell our minds when we look at this in different ways.

* Digression: I started using http://del.icio.us/
about 2 months ago to manage my bookmarks across browsers. I use the laptop mostly but I'm in the home office, the office, and the daycare enough to want to get to my bookmarks no matter where I am.
I took note of http://del.icio.us/popular/ this week. Basically, links that are added often and recently appear in this category. You could say it's like a group of people who sit around and talk about the cool sites on the internet and give out the URL's.... except no one is actually talking.
