Actor Shia LaBeouf, together with Jaden Smith, just launched a four-year-long live stream protesting Donald Trump.

After the 45th President’s inauguration, LaBeouf unveiled the stream with the title “He Will Not Divide Us”. The art project coincides with other celebrities protesting the Trump presidency, including  Rihanna and Stephen Fry.

Staged outside New York’s Museum of the Moving Image and open 24/7, the public art project invites passersby “to deliver the words ‘He will not divide us’ into a camera… repeating the phrase as many times, and for as long as they wish.”

“In this way,” the live stream site explains, “the mantra ‘He will not divide us’ acts as a show of resistance or insistence, opposition or optimism, guided by the spirit of each individual participant and the community.”

Will Smith‘s son Jaden kicked off the project, reciting the mantra for nearly three hours in front of onlookers.
