The USA Today site has an interesting Flash presentation illustrating the growth of the International Space Station from 1998 to the present. It includes a clickable timeline which highlights each chunk of the ISS and gives a bit of background on its purpose. Many of the popups also provide a 360-degree view of the equipment in question.

It’s astonishing to see how much the ISS has expanded over time.
