If you are not familar with navigating information spaces here are a few directions to see some interesting cyberspaces.

These virtual 3-D maps allow full navigation of large information spaces through a three dimensional scenario.

These 3-D spaces are based on the Antarctica Map.net visualization engine:

1) Visualize/Browse/Search the Open Directory Project (ODP)

2) Antarctica Technology Powering an Interface to Canadian Venture Capital Data

3) Visualize, browse and search the Stacks of Belmont Abbey College
