Yeh, they're all max_gradient errors.  I was using 1 during testing, but 
even upping it to (IIRC) 5 in the final render they were still there.

Yep, I would just choose one of tunnels and move the camera along the centre 
line, should work assuming no huge noise part overlaps the centre of the 
tunnel.  A better way would be to find the maximum value of the isosurface 
at each xy slice and put the camera there.

About 20 mins, but a smaller one with less AA and lower max_gradient should 
be way quicker.
