This 755-foot tall building is actually two interconnected skyscrapers built at an angle and then joined at their tops, forming a continuous loop that houses offices in both the vertical and horizontal sections. It's one of the many instant architectural wonders that Beijing has crafted for the Olympics. You've got to see the weirdness on that top section where horizontal meets vertical. Closeup below.

Owned by China Central Television, the looping building has space for 10,000 workers, and will be one of the tallest buildings in Beijing, already known as a skyscraper-friendly town. I love all the strange criss-crossing lines and the one area where you can see that the building isn't entirely finished. It seems to have been built from the top down — at least, when it comes to installing the final windows. Photos by Greg Baker via AP.
