If you're going to watch, I recommend clicking the "fullscreen" icon for best effect. Some will find this boring and give up after a minute or two. I watched the full 30 minutes, with the video at fullscreen and my face close to the monitor, and felt like I was in a different world. I imagined what it would have been like to be one of these people on the street, and how radically their lives would be transformed in the following twelve years.
Addendum: The original embed is down - not sure if that is permanent. In the meantime you can use this link to access the same video (in I think a lower resolution), but it autostarts beyond the midpoint, so you would need to click the timeline to backtrack.
