20. The user interface of claim 2 , wherein said user interface further comprises: a simulation of a three-dimensional navigational space that enables said user to navigate through by any of moving forward/back, right/left, up/down, and rotating; wherein said navigational space comprises a plurality of graphical objects which are any of three-dimensional and animated; and which have sounds associated with them that said user begins to hear as he draws near said object; wherein there are links between said objects representing relationships between concepts they represent; wherein said links are almost transparent; wherein as said user moves near to an object, said links associated with said object become more visible, fading as a chain of connections gets farther from said object; and wherein as the user approaches a link, links of that type become more visible.
