Visual Complexity
Of course, one might argue that this blog doesn't have a point.
All joking aside, I've had a lot of fun reading design blogs recently. These don't provide as much food for discussion for me as music and technology blogs, but some of them are visually stunning and (even more exciting) very few of them deal with design, interface, technology, etc in really new ways.
One of my recent favorites is Visual Complexity. This is what Manuel Lima, creator of the blog, has to say about it:
VisualComplexity.com intends to be a unified resource space for anyone interested in the visualization of complex networks. The project's main goal is to leverage a critical understanding of different visualization methods, across a series of disciplines, as diverse as Biology, Social Networks or the World Wide Web.
Here is a sample of the sort of visual representation that is featured on the site:

We are looking at a representation of the genetic interaction network in the bacteria Escherichia Coli.
The reader is just as likely to come across a representation of bacteria as you would be to see a map of a subway, or of social interaction. It is really neat - check it out!
