To see a higher definition version of the video, go here.
I saw this in the unlikely place “Astronomy picture of the day” labeled “Happy People Dancing on Planet Earth”. The story is this guy Matt Harding, going round the world recording himself dancing in 39 different countries with local people. A lot of fun. As they said in the blurb on Astropix: “Happiness is frequently contagious — few people are able to watch the above video without smiling” (their hyperlinks).
It reminded me of another blog I am currently following “The art of non-conformity” by a guy called Chris Guillebeau who is amongst other things, trying to visit every country in the world.
