A co-worker of mine used to work at Eugene Tsui's office, which is in Emeryville, CA. Judging from the text on the Tsui Design & Research website, Tsui is definitely a character, and it's hard for me to tell if there's any validity in some of his ideas because that constructed persona gets in the way. Anyhow, when he's not playing flamenco guitar, winning senior gymnastics medals, and designing sci-fi clothing, this renaissance man is developing biomorphic architecture. The planning project that caught my eye is for a bridge spanning across the Strait of Gibralter. Here's an aerial view of a model of what it would look like:
The spans are actually underwater, arched tunnels linked by a floating island in the middle. Here's a section view:
These fish-shaped tunnels would not only have car lanes and train tracks but linear parks for people to move through, complete with trees, pools, waterfalls, and areas for music and dance performances. The whole project would, according to Dr. Tsui, double Spain's tourists, increase Morocco's by 2600% and would "no doubt be the Eighth Wonder of the World".
