In 1977, the Eames' made a great movie called Powers of 10. Starting with a sleeping man at a picnic, the film takes the viewer on a journey out to the edge of space and then back into a carbon atom in the hand of the man picnic, all in a single shot.
Today, we can experience Nano Journeys, an interactive tour into the worlds of the micro- and nano-cosmos. Three different tours lets us scale down into the human arm, into a computer processor, or into the LED of a car's headlight to discover the smallest dimensions of our universe.
The latter journey is part of an information campaign by the German Federal Ministry of Education and Research to inform the larger audience about the research and everyday impact of nanotechnology.
