Universcale

The people over at Nikon made a website that allows you to see things ranging from the size of the Universe to a neutron, in scale. You can compare a Sequoia Tree to the Statue of Liberty, or a Double Deck Bus to a Giraffe. It's neat to see the size of things in comparison to others. For example, the Sphinx isn't all that big. The website is well laid out and runs very smoothly. Worth checking out for a few minutes.
