New York City portal descends into utter chaos as OnlyFans model flashes breasts at Dublin - while Irishman is seen sniffing powder through the screen

Raunchy behavior is on full display at the 'portal' art installation connecting New York City and Dublin - with one woman shutting down the stream after flashing her breasts.

The futuristic sculpture forms a 24/7 virtual bridge that livestreams life from across the Atlantic, allowing people to connect despite being thousands of miles apart.

However, many locals on both sides of the portal have been abusing the technology.

New York City's Portal is located in front of the Flatiron Building on Fifth Avenue and Dublin's on O'Connell Street in front of the GPO and the Spire.

Since being activated on May 8, onlookers were quick to turn the well-meaning project into a hotbed of shocking behavior.

Social media has been flooded with videos of people flashing their bare bottoms or tops - and allegedly engaging in illegal substances. 

In one case, OnlyFans model Ava Louise posted a video of herself lifting up her top and showing her breasts to the portal with her naked back facing the New York City crowd.

'I thought the people of Dublin deserved to see my two New York homegrown potatoes,' Louise said.

The stream appeared to shutdown after Louise was caught flashing Dublin, with one person telling her boyfriend 'it's very unfortunate people are not acting in the best way.'

Another video posted to Instagram showed a man on the Dublin side snorting an unknown substance, saying, 'what a day, what a city, New York never sleeps.'

The usual view of people waving from the historic Irish capital was interrupted within hours of the portal opening by a closeup of a man's phone.

First it displayed 'RIP Popsmoke', referring to American rapper Bashar Barakah Jackson, who was gunned down in a home invasion on February 19, 2020.

Five men stormed Jackson's house in Los Angeles demanding jewelry and shot him three times with a Beretta M92 when he tried to fight them.

The Irishman then switched the view on his phone to a video of the World Trade Center towers burning and billowing with black smoke during the 9/11 terror attack which rocked the city and the world in 2001.

Another video from the Dublin side of the portal showed a woman being dragged away from the portal by police after grinding against the screen.

'Basically she was there for about 20 minutes very drunk and was slapping and grinding against the portal before guards stepped in,' the person who filmed it explained.

Less extreme was an Irishman who waved at the dozens of Americans on the other side, before turning around and mooning them.

Another man held up a swastika on his phone, and plenty of middle fingers were exchanged on both sides.

Amidst the shenanigans of varying degrees of offensiveness, there have been some wholesome moments captured on both sides of the portal.

In one case, a man in a rainy New York was seen being cheered on by people in Dublin as he smashed out 50 push ups. The Irish crowd were seen giving him a round of applause as he stood up triumphantly.

In another clip, two friends - one in New York and one in Dublin - were seen meeting via the portal. The video was captioned: 'meeting up with my Irish bestie through a portal' - and showed the two women making heart symbols with their hands.

The displays will operate through the fall, but an official end date has not been announced.

'Portals are an invitation to meet people above borders and differences and to experience our world as it really is - united and one,' said Benediktas Gylys, a Lithuanian artist and founder of The Portal.

Gylys first thought of the concept in 2016 when a spiritual experience led him to view the planet through a different lens and he developed the need to 'counter polarizing ideas' and find a way for people from different cultures to communicate.

He provided the majority of the funds needed to build the first two portals in collaboration with a team from VilniusTech University in Lithuania.

The first two portals opened in May 2021 in the Lithuanian capital Vilnius and in the Polish city, Lublin.
