Some say that the photograph of the Earth floating in Space shot from Apollo 8 kick-started the environmental movement, showing that we were all in it together on such a small blue marble. Others have said that Charles and Ray Eames' Powers of Ten taught us about scale, our small place in the universe. Kottke reminds us that no matter what you watch, the original Eames version shown above, the fabulous and funny Powers of Ten Simpsons on the Couch version, or the National Film Board 1968 version by Eva Szasz, shown below, they all put us in our place.

Thanks to ::Kottke.org for the memories.
from the ::Simpsons version
UPDATE: Commenter Andrew MT tells us about another version: "I saw this IMAX film (when I was around 15 or so) before I saw the original Powers of Ten, and I must say that the improved computer generated graphics, beautiful music, and narration by Morgan Freeman blow the original film out of the water."
