The Tornado Tower is a design for a performing arts center in Taipei, Taiwan, and man is it crazy. That huge bubble on top is where the theater sits, and the whole thing harnesses the wind for energy.
The entire exterior is covered with curved fins that generate wind energy while also making it look like a huge cloud. At least it would be, if it was selected as the winning entry in the contest to design the performing arts center. Which is wasn't. But still, it's a pretty stunning design. [Plus Mood via Inhabitat]
