Yep, I blew it -- neglected to check my work. Scratch all of my
previous emails on the subject.
The following function (turn_y_light.py) will correctly rotate th

Warren's script is not quite right. The value -0.902 is not correct.
Apparently, my picture, with a stick peptide casting a shadow on the inner
surface of a deep crevice, is particularly demanding.
I have done the vector calculations. See the attached excel worksheet for
light vectors for a
Scott,
PyMOL's lighting model is merely a direction, not a point. The default
direction vector isn't even normalized to unit length.
In the script I just posted, I used unit vectors to specify the light
direction and simply rotated that vector by 6 degrees. The first vector
is merely [-0.4,-0.4
