By day, Thomas Dimson quietly works on Instagram's data, trying to understand how people connect and spread content using the service. Like a lot of people working at the company, he's also a photo and movie geek?and one of his longest-held affections has been for Baraka, an art-house ode to humanity that features epic tracking shots of peoples all across the world. "It was my senior year, and my friend who was an architect said, 'You have to see it, it will blow you away,'" says Dimson. He wasn't entirely convinced. The movie, after all, was famous for lacking any narration or plot. But watching the film in his basement, Dimson was awestruck. "Ever since, it's always been the back of my mind," he says.
