Something I saw while walking the dog: This sticker on the side window of a car.

When you’re watching TV show set in or around 1970 and Doors music comes on, something bad is gonna happen. When the Doors song is “People Are Strange,” somebody’s gonna OD.

Tokyo University graduate student Takatsugu Kuriyama built an accurate three-dimensional model of Tokyo’s incredibly complex subway system “using multi-colored tubes strung with wire. Different color liquids pulsate throughout all 18 lines, creating a staggering picture of what goes on below the streets of Tokyo every day.”

Looking at this diagram, I realized that I visualize subway systems (like Tokyo’s, New York’s or London’s) operating on a single plane. Flat. But Tokyo’s, at least, is tall as well as broad. It’s like an anthill or termite’s nest.
