Every second, an incredible number of interactions take place on the internet, and "One Second on the Internet" gives you a real sense of their scale. It's a website which displays an icon for every single Facebook like, Google search, YouTube video watched, email sent, and so on, over the course of a single second. Just scroll down the page, if you have the patience, to get an idea of just how quickly the web moves, and how quickly it continues to move while you watch. It's not nearly as humbling as, say, seeing the Earth from space, but it's definitely worth seeing once.
