Walk down the street in New York City today, and your likeness will be captured on camera dozens of times over the course of a routine afternoon. You will pass security lenses affixed to building facades, overhead traffic lights monitoring the flow of vehicles, and subterranean transit hubs where more than 4,000 closed-circuit television cameras track your every movement. There are specialized security gadgets inconspicuously planted in elevators, grand hotel lobbies, neighborhood coffee shops, and late-night convenience stores, all of which maintain a constant, watchful eye on the urban populace.
Across the United States, an estimated 62 million security cameras monitor public and private spaces alike, creating an invisible, omnipresent web of observation. This vast network means that at any given moment, you are probably being watched without even knowing it, your movements recorded and cataloged by machines. It is almost like a modern, high-tech and dystopian version of the classic fairy tale Hansel and Gretel, where everywhere you go, you leave a continuous path of digital breadcrumbs in your wake.
We often do not see or consciously think about these cameras as we go about our daily routines, treating them as mere background noise in an increasingly digitized society. However, a major exhibition at New York City’s historic Park Avenue Armory puts this pervasive surveillance state overtly and dramatically on display for the public to experience firsthand. For an ambitious art project appropriately titled Hansel and Gretel, renowned artist Ai WeiWei and acclaimed Swiss architects Jacques Herzog and Pierre de Meuron have transformed the Armory’s cavernous, industrial drill hall into a sprawling, interactive surveillance park.
Inside this darkened sanctuary, a complex network of 56 tiny computers attached to infrared cameras and high-powered projectors hang precariously from the soaring rafters above. Meanwhile, a handful of tethered, motorized drones buzz ominously overhead, continuously capturing real-time footage of the visitors wandering below and feeding that digital imagery directly back into a live stream displayed throughout the hall.
As visitors wander through the dim, cavernous room, these concealed cameras capture their exact likeness and cast ghostly, transient renderings directly onto the concrete floor beneath their feet. A complex grid of projected red boxes and stark white lines frame each individual person, serving as an unspoken, technological acknowledgement of the modern surveillance apparatus’s ability to precisely pinpoint a human location in real time.
“It’s the physicalization of surveillance,” says Jacques Herzog, who, alongside his architectural partner Pierre de Meuron and artist Ai WeiWei, aimed to construct an active, participatory surveillance state within the walls of the cultural institution. The core conceptual goal behind the project is simple yet profound: ordinary people should be given the opportunity to see firsthand the exact kind of sophisticated technology that tracks, records, and analyzes them on a daily basis without their explicit knowledge or consent.
Surveillance on Display
Watchdog technology has proven to be a remarkably rich area for contemporary artists to mine, largely because it occupies a strange dual space in modern life—it is simultaneously so pervasive that we take it for granted and so invisible that we rarely notice its lens.
The knee-jerk, traditional response for artists working with these themes is to use the technology as a shocking tool of revelation—a clever bait-and-switch designed to deliver the delayed, unsettling truth that something has been secretly watching you all along without your knowledge. Yet with Hansel and Gretel, the creators seemingly sidestepped that predictable trope. Instead, they made the underlying technology an entirely obvious, transparent component of the physical visitor experience.
The fact that every single person in the hall was being actively monitored was no secret whatsoever, a design choice that paradoxically made it remarkably easy for visitors to work the intrusive technology directly in their own favor. All around the vast drill hall, people eagerly paused for eerie, staged photo shoots. They stood posing, smartphone in hand, smiling and gesturing as the overhead security cameras snapped their picture and instantly replicated it in real-time on the ground below them.
Despite the enveloping darkness, the sudden flashes of light, and the genuinely ominous mood cultivated within the space itself, the overall environment inside the Armory felt surprisingly convivial. Rather than inducing paralyzing fear, anxiety, or deep-seated paranoia about the loss of privacy, the immersive installation effectively turned state-grade surveillance into an extension of everyday selfie culture.
“There seems to be an ambivalence [towards surveillance],” observes Tom Eccles, the show’s curator, reflecting on the surprising public reaction to the heavy-handed monitoring. “Maybe that’s the way the world has changed.”
After finally exiting the main exhibition hall, visitors shuffle toward another entrance corridor within the Park Avenue Armory, where an unassuming usher cheerfully greets them to continue the process.
“Hi there, could you put your toes on the line and look straight ahead for me?” the staff member asks with an inviting, polite smile.
Looking straight ahead reveals yet another hidden camera, this one engineered to capture a sharp, high-resolution, straight-on headshot. Just minutes later, this captured portrait is projected directly onto the large digital frames that line the walls of the Armory’s secondary rooms. Positioned on tables directly below these glowing frames, a neat row of tablet computers invites visitors to take yet another selfie, which is immediately fed into an advanced facial recognition software program designed to search a database for a matching digital image.
Within mere seconds of pressing the button, the researcher’s face pops up neatly on the screen, matched to the photograph taken just moments prior in the hallway. The computer’s underlying algorithmic software proudly announces it is 52 percent confident that the image is an accurate match.
For some visitors, the sudden, jarring immediacy of this biometric recognition will undoubtedly feel unsettling, reinforcing just how rapidly our physical identities can be processed by machines. However, any lingering creep factor or existential dread tends to subside almost immediately when a brightly colored pop-up box unexpectedly emerges on the screen. For a modest fee of $10, visitors are informed that they can easily purchase a high-quality physical print of their newly generated recognition photo directly from the museum’s gift shop on their way out.
