New York: More than a dozen millennials gathered in a brownstone apartment in Brooklyn and placed their phones in a metal colander before two hours of reading, drawing and conversation - anything but staring at screens.
A similar scene played out a few miles away, in an early 20th-century cardboard box factory turned high-end office space. Nearly 20 people in their 30s stared at their cellphones for a few minutes. Then they set them down and looked at their bared palms for a while. Then those of their neighbors.
The exercise was meant to drive home the importance of paying attention to real life, not the gleaming little screens that have taken over our world.
Two decades after Steve Jobs premiered the iPhone, a small but passionate movement - with offshoots in several countries - is rebelling against the omnipresent screen.
"The products have become more insidious and more extractive, exploitative," said Dan Fox, 38, who hosted the house gathering. Members of the nascent movement "want to start a revolution," he said.
But can an "attention activism" movement of millennials and Generation Z members break free of the world's largest companies? The raw numbers say no. But cultural changes start small, and the rebellion is growing against what many call "human fracking."
Apple and other Big Tech firms say they've taken steps to help users reduce time spent on their devices, including features that track usage and a less enticing gray mode.
Activists say it's not enough.
"They want to take down Big Tech," says Fox, a stand-up comedian who works in marketing for Brooklyn-based Light Phone, one of several "dumb phones" with only basic functionality.
Unlike most modern products, the company boasts of its phones' lack of features, like "social media, clickbait news, email, an internet browser, or any other anxiety-inducing infinite feed."
Fox was inspired to join the movement when he attended a 2015 Tame Impala concert at Radio City Music Hall. It felt as if everyone in the audience was filming the concert on their phones instead of immersing themselves in the music.
"I realized the phones are literally getting in the way of the things I love," Fox said.
Mobile internet access has so thoroughly permeated modern life that one of the few places in the world where it's not readily available is wartime Iran, where authorities shut down the internet during mass protests in January.
Graham Burnett is a historian of science at Princeton University and one of the authors of "Attensity! A Manifesto of the Attention Liberation Movement," making him a pillar of the growing backlash against the corporate harvesting of human attention.
Along with MS NOW host Chris Hayes' bestselling "The Sirens' Call: How Attention Became the World's Most Endangered Resource," his work is part of a growing body of literature calling for people to move away from screens and pay attention to life.
Burnett says the "attention liberation movement" is about throwing off the yoke of time-sucking apps. People "need to rewild their attention. Their attention is the fullness of their relationship to the world."
The people in Fox's living room started the evening by introducing themselves, as if at a support group.
"I don't feel good about my relationship with my phone. I feel like an addict," said Riley Soloner, who teaches theatrical clowning and works as an usher at Carnegie Hall. He arrived with a backpack full of books - the paper kind.
