Construction is nearly complete on the Beijing Olympic Stadium, shaped like a massive steel bird's nest, and the swimming-pool-filled Water Cube, which looks like a piece of glowing alien machinery. This is an actual photo of the buildings at night. We've also got some less-surreal glimpses of them too.
Here you can see people posing in front of the Nest last week.
And here's a closeup of the crisscrossed steel girders that form the exoskeleton of the Nest.
The Water Cube is actually made of high-tech materials that emulate bubbles to keep the heat inside the building.
