I love when a site unexpectedly shows me a little bit of code. I found this one on wired.com, of all places, in an article about Tim O'Reilly, of all people. Stumbling onto unrendered code is like watching a utility worker opening an access panel in the sidewalk. Beneath the skin of our orderly lives is a secret world, ugly and messy, of wires and code, that makes it all tick. This is what I loved about Berlin (and Zagreb, and Budapest): the interior is so close to the skin. Wires and code peeking out everywhere. I'm sure this is a huge problem, maintenance-wise (if I can see it, it's probably getting rained on...), but I love it nonetheless.
