If you’re afraid of heights, a mere glance at these photos taken by Russian daredevil photographer Angela Nikolau might be enough to give you the heebie-jeebies. The 23-year-old scales some of the tallest skyscrapers in Russia and Asia, either using a selfie stick, a drone, or bringing her boyfriend Ivan Kuzenetsov along to take the photos. And as if perching on the edges of structures at such extreme heights isn’t enough, she often does yoga poses or wears stilettos while doing so.

The self-taught climber is not too concerned about bypassing security and breaking trespassing laws to capture these incredible images, and virtually no building is too tall. Angela and Ivan climbed all 2,000 feet of the Golden Finance 117 building in Tianjin, China last fall.

Other illegal conquests include the Sagrada Familia in Barcelona, the Shanghai Tower in China, the Tsing Ma bridge in Hong Kong and the Eiffel Tower in Paris. Unsurprisingly, many of the photos have to be taken late at night to avoid being caught.

Angela’s casual poses might be the most disconcerting aspect of the photos, especially for those of us who imagine death-gripping the edge if we managed to make it up that high. She’s often lounging dangerously close to certain death, holding on to a ladder with just one hand or hanging barefoot off cranes. In some images, she’s held aloft by her boyfriend, dangling hundreds of feet off the ground.

“This isn’t fake, I promise,” said filmmaker Casey Neistat as he announced the impending debut of his ‘Human Flying Drone Holiday Movie’ on Twitter with a dubious-looking graphic. Anyone who saw that tweet could be forgiven for their skepticism, especially since Neistat was teaming up with fellow YouTube star Jesse Wellens of the channel PrankvsPrank to pull off the stunt. But by all accounts, this footage of the ‘world’s largest homemade drone’ is real, and a Santa-suited Neistat is actually flying 25 feet in the air.

No one in the world sells a drone that can lift a human being, so Neistat and his team set out to create one. The octocopter drone, which is augmented with a Samsung Galaxy Gear 360 action camera, reportedly took over a year to build, and the video clip was shot at a ski resort in Finland over the course of four days. In it, the daredevil YouTuber zooms down a slope on a snowboard and then takes off into the sky, going higher and higher before the final jump takes him 100 feet into the air, as smoke bombs fastened to his feet emit vivid pink plumes.

One thing that’s not quite what it seems is Neistat’s single-handed grip on the handle: he’s actually securely fastened to the drone, dubbed ‘Janet,’ by a body harness. The rest of it, as far as anyone can tell, is legit. Looks like fun! Check out how it’s done in the behind-the-scenes video above.

The first-person perspective seen on this video of two dancers vaulting effortlessly off the side of Oakland’s City Hall building might make you a little dizzy. Secured to the 18-story structure’s roof with safety lines, the duo run, flip and seemingly fly, captured from various angles that can be a tad disorienting.

The pair are members of the Bandaloop vertical choreography dance company, which staged the performance for the Art + Soul Festival in Oakland, California. GoPro cameras capture the action in all its elegance.

The company aims to “re-imagine dance,” performing these seemingly weightless feats on skyscrapers, bridges, billboards, cliffs and historical sights. Says founder and artistic director Amelia Rudolph, “They say what we do is death-defying. I’d say it’s life-affirming.”

The images and the videos of the performances are breathtaking, particularly those of dancers rappelling off the 217-foot Santiago Calatrava ‘Sundial Bridge’ in Redding, seen above. Check them all out at the Bandaloop website.

A new video and set of photographs is circulating from St. Petersburg, Russia, where the Parkour movement is gaining a strong foothold among the city’s youth. The video shows a young man jumping from one rooftop to another, with 35 feet of height difference and about 20 feet of space between the buildings.

It’s inspiring mixed feelings from the public and from Parkour enthusiasts. While the stunt was impressive and the stuntman seemed to know what  he was doing, it was incredibly dangerous. But the group featured in the video say that they were trying to raise awareness of the sport and point out the problem of a lack of safe, sanctioned places to practice it.

This Russian news story shows another side of the stunt. The man doing the first jump pulled it off perfectly without any problems, but when a friend tried the same jump he injured his leg. We don’t speak Russian so we’re not sure what the newscaster is saying, but judging from his tone it’s not entirely positive.

Parkour is generally seen as a physically challenging sport that’s somewhat dangerous, but not overly so. This video of Austrian traceur Sacha Hauser shows that Parkour isn’t just about taking the biggest risks and evoking the biggest reactions – it’s also a beautiful, artistic use of the human body’s strength.
