Accuracy was originally set to 0.0001; I also tried values several 
powers of 10 smaller, as small as, 0.0000001, but instead I just got 
strange grainy shadows. Currently, I render at 0.001 (default)... the 
two images below show what I got with (first) and without (second) 
double_illuminate for the isosurface.

The camera looks eastward, the sun is 25 degrees above the eastern 
horizon, so the version without double_illuminate looks more believable 
to me...

See you in Khyberspace!
