This is the link to the New York Times page with all the videos: http://www.nytimes.com/interactive/2010/12/12/magazine/14actors.html
And here is a blogpost about the details of the production: http://community.livejournal.com/ohnotheydidnt/54113481.html
I went through the videos before looking at all the preview pictures, so I watched the whole series without any expectations.
Of course, I liked some more than others. But what stood out the most, to me, is the music. It works so perfectly with the videos and makes the lack of dialogue not an issue. It creates mood and at times add a little humor.
Most of the videos are so intense they can make you forget about your surroundings and dive into their world/situation.
It was a great production indeed.
