... a big-city version of a drive-in movieNavid Baraty
Answer: B. Launched in 1993, New York City's annual Bryant Park film festival now attracts more than 100,000 viewers each summer--and that's not counting those watching from the rooftops. Leaning over the edge of a nearby skyscraper, photographer Navid Baraty gets this rare pigeon's-eye view of the moviegoing masses staking their territory hundreds of feet below. "After seeing countless skyline photos of NYC," Baraty says, "I found that the real life of the city can best be captured by pointing the lens straight down from high above."

Gravity is no match for these alpine ibex goats. They typically live in very steep, rocky terrain, so this 160-foot-high, near-vertical dam in Northern Italy doesn’t faze them as they roam, licking the stones for salt.

Spring has clearly sprung in Zuid-Holland, as these vast tulip beds attest. Although the flowers originated in Central Asia, they’re big business—and a major tourist draw—in the Netherlands from April until early May. Some three billion bulbs (red, white, yellow, green, purple, and more­) pop up there each year. But a tulip, like spring, is fleeting; it blooms for only a few weeks.

Most people go to the beach to chill, but tourists who flock to Maho Beach on the Caribbean island of St. Maarten go for thrills. Low-flying planes heading for the adjacent airport can actually blow sunbathers into the water (at least that’s what local government signs warn).

They look like veins, and in a way, they are. Google software engineer Nelson Minar created this digital map showing all the rivers in the United States, along with dry stream and creek beds. The previous close-up shows the Mississippi River in New Orleans. Minar's goal was to demo new technology, "but it's also kind of pretty," he says modestly.

... car rust.
Rust by any other name can be beautiful. But when water, air, and steel get together and do their thing on your car door, you might not view it so kindly! Metals corrode in damp conditions, but only iron and iron alloys (like steel) rust. Most people consider rust to be reddish, but it comes in a panoply of hues.

... millions of monarch butterflies.
Every fall, millions of monarch butterflies head south from Canada and the United States to their winter digs in Michoacán, Mexico; here they make strange shapes on the trees in the region's Sierra Chincua preserve. Scientists didn't discover the monarchs' wintering grounds until 1975—and they still don't understand how the winged things know where to go. Sadly, they're in decline, occupying a record low 2.9 acres, down from some 22 acres a decade ago.

Some people chew on pencils; others turn them into art. “I saw that I could make long, undulating shavings with a sharpener, and I started gluing them to a surface,” says photographer Levi Brown. “Initially, I was going to make a pattern with them, but they started to take on a life of their own and formed a topography.” Attention, students: Don’t try this at school.

If you ever happen to look a llama straight in the eye, you'll see an unusual pupil: a horizontal oval that might be sky blue. The squiggly frills surrounding it are called iridic granules, and they're believed to provide shade in bright sunlight. The close-up on the previous slide was photographed by Suren Manvelyan, who has shot the peepers of creatures from pythons to people.

Using a plastic bottle filled with salt, Japanese artist Motoi Yamamoto painstakingly draws massive, lacy labyrinths on museum floors. Salt—symbolizing the transience of life—is used in Japanese funeral rituals. Yamamoto was moved to make his saltscapes in honor of his sister, who died at a young age. After each creation is displayed, the salt is thrown into the ocean.

From high above, the fish traps in Kosi Bay, South Africa, form a mysteriously lovely pattern on water rich with algae. Generations of fishermen have worked in the bay—really a series of four interlinking lakes surrounded by a nature preserve. The area is known for biodiversity: In addition to abundant spotted grunter, rock salmon, and bream, it's home to 250 species of birds, plus crocodiles and hippos. Happily, trap fishing is both successful and sustainable.

Hint: The shoes are the giveaway. Chinese artist Liu Bolin camouflaged himself for a series of photos called Hiding in the City. They're metaphors for government suppression of art, he says. Other scenes he's painted himself into include the rubble of earthquakes in the countryside and a wall with text from The Communist Manifesto scrawled on it.

The Bahá'í House of Worship in New Delhi, India, is known as the Lotus Temple: It's composed of 27 marble "petals" surrounded by nine ponds. Designed by Iranian-born architect Fariborz Sahba (who now lives in Canada), the temple has attracted tens of millions of visitors since opening in 1986. Photographer Nicolas Chorier shot these images from a camera affixed to a remote-controlled kite.
