Fed up with politics?

Overwhelmed by social networking? ("I need to know what is important, and I don’t have time to sift through thousands of Tweets and Friendfeed messages and blog posts and emails and IMs a day to find the five things that I really need to know.")

Imagining the Tenth Dimension. I dare you.

Too heavy? Try old Johnny Cash.

Vaguely related: If it's too early to wrap your brain around even three dimensions, check out the Quilts by Caryl Bryer Fallert using the Fibonacci Progression in their designs. That second link is full of photos of shells, flowers, pine cones and vegetables that illustrate the concept even if, like me, you don't think well in numbers.
