Pink

From an interview with architect William McDonough over at New Scientist.

"Being less bad is not the same as being good."

"From my designer's perspective, I ask: why can't I design a building like a tree? A building that makes oxygen, fixes nitrogen, sequesters carbon, distils water, builds soil, accrues solar energy as fuel, makes complex sugars and food, creates microclimates, changes colours with the seasons and self-replicates. This is using nature as a model and a mentor, not an inconvenience. It's a delightful prospect."

"We should also celebrate the diversity of the world. We want 400 kinds of French cheese. What we don't want is 400 kinds of French polymer."

Not completely unrelated there's a story over at optics.org about see-through cement.
