Clouds love to talk about the shapes cities remind them of; Inside North Korea

Gravity, love, freedom, all the greatest forces are invisible.

Inside North Korea, a documentary aired in April 2013. A reporter goes undercover into a place clothed in mystery and unanswered questions: North Korea. The dark spot on a map, the ultimate Orwellian state, the never-ending hunger crisis, the brainwash machine...Only guesses, each grimmer than the previous. What's the truth? Taking us just a few steps closer to really understanding the minds of North Korean leaders and most importantly, the minds of the people, BBC Panorama Documentary.

Another thrilling story to illustrate just how difficult it is to escape the authoritarian state, the story of Hyeonseo Lee "My Escape From North Korea", a TEDtalk: 

"Fantasy. Lunacy. All revolutions are until they happen, then they are historical inevitabilities."
