179  These techniques together make it possible to implement a  Starting from three simple principles:
180  new focus+context user interface with two important features.  
181  First, all connected information is visible in fine detail  - the user should always see [fragments of] all link targets
182  --- you always see everything where you can go.    "you should see where you can go to"
183  Second, all view changes are fluidly animated without discontinuities  
184  and local spatial structure is approximately maintained in transitions.  - the link transition should be fluidly animated, so that the
185      visible link target comes to the focus
186      "you should see how you go there"
187    
188    - the link transition and resulting view should make it obvious to the user how
189      to go back, without a "back button" [implies bidirectional links]
190      "once you get there, you should see how you can get back"
191    
192    we apply and develope a number of user interface techniques
