Powers of Ten

Florida State University's "Molecular Expressions" Web site offers a fascinating sequence of images, each one 10 times bigger or smaller in scale than the one preceding or following it. The journey ranges from a view of the universe 10 million light years away from the Milky Way to an impressionistic glimpse of a diminutive sea of quarks. Requires a Java-enabled browser.
