 \begin{abstract}
 We introduce unique textures: procedurally generated textures based on  
-- for identity (displaying etc)
+node identity,
+for assisting user orientation
+in navigating hyperstructures using Focus+Context views.
+%
+We can generate a texture for every document the user ever visits,
+and the user will be able to learn the textures of the 
+most often visited
+documents, as per Zipf's law.
+%
+In Focus+Context views, the textures can act as visual cues in the context
+(information foraging).
+
+We have designed a hardware-accelerated implementation of unique textures
+using a rough, qualitative model of visual perception.
+The implementation works by combining a small set of basis textures
+on the GPU.
+
+% - saving bits
+% - colors decoupled
+% - perceptually uniformly chosen
+% - repeating non-repeating
+% - render-to-texture

+% Unique textures can be implemented by combining a small set of basis
+% textures on the GPU. We discuss our implementation on the NV10 and NV20
+% architectures.
