A friend of mine sent me this and I thought you would enjoy seeing this link.
The Florida State University, Tallahassee, Florida has put up a very interesting Java applet on their site. It begins as a view of the Milky Way Galaxy viewed from a distance of 10 million light years and then zooms into towards Earth in powers of ten of distance. 10 million, to one million, to 100,000 light years and so on and then when it finally reaches a large Oak tree leaf. But that is not all it zooms into the leaf until it reaches the level of the quarks viewed at 100 attometers.

This is a fantastic representation of how magnificent the Universe is and how vastly infinite it is both in the macroscopic and the microscopic level.
