Bridges as walls The biographer of Robert Moses, Robert A. Caro, refers to the bridges and underpasses of the famed New York State parkways. These bridges and underpasses are quite low, intentionally specified by Moses to allow only private cars to pass. All those who traveled by bus because they were poor or black or both were barred from the use and enjoyment of the parkland and its "public amenities" by the technical design of the bridges. Even at the time of Robert Moses, a political statement of the form "We don't want them blacks in our parks" would have been unacceptable in New York State. But a technological expression of the same prejudice appeared to be all right. Of course, to the public the intent of the design became evident only after it was executed, and then the bridges were there. Ursula M.

An ecological cycle In the design of his own residence / workplace, Toshiharu Naka created a small ecological cycle. Rows of green planters in front of the wall protect the house from the sun and help cool it in summer. Rainwater is collected via catch-basins from the roof, and used to water the planters. In the water buckets is a micro-cycle — fish live in the buckets, eating mosquitos from the planters, eliminating the need for pesticides. Toshiharu Naka, Two Cycles Turn them into cycles
