I'm sorry, I know it's lame, but the old silo is my first actual modelling attempt, and I wanted to use it. :P Does anyone know if there's somewhere you can see pictures of all the precedural texture components included in Bryce? When I want a particular type of effect or map, it seems all I can do is pick through the possibilities randomly.

If you hold down the "shift"key while klicking with the mouse to the triangle with which you open the textures in matlab, you can see a preview

Thanks! :) That helps a lot!

The other way to get to that dialog is to go into the DTE and click on the upper-right-side button on the central preview (i.e. the preview showing all the components mixed together). The lower-right-side button randomizes the texture, which can be a fun way to get wacky effects.
