In North Korea, the choreography can be part of the geography.
The country is famous for organizing crowds of thousands of people using colored cards to spell out political slogans and images in stadiums or large squares, and the gathering last week to celebrate the 100th birthday of national founder Kim Il Sung was no different.
This time, however, the spelled out message in a central square in the capital of Pyongyang was big enough to be visible from space.
An April 15 image of a celebration taken by a satellite and distributed by DigitalGlobe shows people in red and gold clothing gathered in Kim Il Sung Square and spelling out the word "glory" in Korean.
The parade culminated with the unveiling of a new missile, although analysts who have studied photos of a half-dozen ominous new North Korean rockets say they were fakes.
