In addition to the book he gave the head of the Roman Catholic Church during their visit yesterday, Facebook founder Mark Zuckerberg and his wife Priscilla also gave Pope Francis a Facebook-themed drone (pay attention to the glee on Pope's face).
"Priscilla and I had the honor of meeting Pope Francis at the Vatican. We told him how much we admire his message of mercy and tenderness, and how he's found new ways to communicate with people of every faith around the world.
"We also discussed the importance of connecting people, especially in parts of the world without internet access. We gave him a model of Aquila, our solar-powered aircraft that will beam internet connectivity to places that don't have it. And we shared our work with the Chan Zuckerberg Initiative to help people around the world.
"It was a meeting we'll never forget. You can feel his warmth and kindness, and how deeply he cares about helping people."
