Thanks to The Science Pundit for alerting me to this amazing animation (now also for sale as screensaver):
Secret Worlds: The Universe Within:
View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida.
