There are tunels that seems perpendicular to the one you travel, but most 
intersect at a sharp angle.
Possibility: generate the main tunel.
Randomly generate a cluster of points around it's path, in a radius about twice 
the radius.
For each point, select a random direction and curvature. Possibly add some 
radius variance.

At times, you bet filled whireframe, and the mesh resolution is fairly low at 
"high" quality. If you deselect "Disable hair effect", you get small sticks at 
the triangles angles that seems to corespond to the normals.
