Dude. This rawks! Click on over to check out this neato zoomie thingy from the University of Utah. You start with visible objects like coffee beans, and zoom in on smaller and smaller things.
Nice! But I could never wrap my head around the very large or the very small or the very long or the very anything. (Hat tip to Neil Jenkins.)
