+In order to avoid shapes or features from the basis textures becoming 
+identifiable, the basis textures should be relatively uniform.
+We have obtained good results with a mix of
+small textures with uniformly random texels, 
+larger textures with noise or turbulence\cite{perlin-noise-intro}, 
+and simple geometric images (checkerboard, cone).
+
+As for selection of basis textures for each paper, the principle of ``saving 
bits'' applies:
+using hyperparameters for each paper to control the probabilities of
+different basis textures so that a paper will have mostly basis textures
+of one or two types will give a specific feel to the paper.
