Yann Arthus Bertrand is well-known for his photos of the earth from above. You may have seen his books, one of which André and I got as a wedding present. The site also offers some of Bertrand’s photos as desktop wallpapers.
I should probably take a closer look at Newton’s Aquarium, which is “an interactive physics package that helps students visualize and understand Newton’s Law of Universal Gravitation. While creating and exploring their own solar systems, students encounter the core concepts in classical physics.”
