No it won't because you're not rotating 360 degress.  Instead, you're =
splitting 720 degrees of rotation about two axes which are constantly =
changing (relative to original orientation).

Try this instead:

mset 1 x72
movie.nutate 1,72,20

>=20

>=20

On the mac version (only?) I think it can be found in =
examples/devel/D01lambda.py (or something similar).
