31  - for identity (displaying etc)  node identity,
32    for assisting user orientation
33    in navigating hyperstructures using Focus+Context views.

35    We can generate a texture for every document the user ever visits,
36    and the user will be able to learn the textures of the
37    most often visited
38    documents, as per Zipf's law.
39    %
40    In Focus+Context views, the textures can act as visual cues in the context
41    (information foraging).
42    
43    We have designed a hardware-accelerated implementation of unique textures
44    using a rough, qualitative model of visual perception.
45    The implementation works by combining a small set of basis textures
46    on the GPU.
