No problem. I am glad that it is useful. Yes, you can have a figure with a
mix of 2D subplots and 3D subplots. I will make sure I include an example
of that as well. I will look into updating the rst file, and also the
current batch of examples to use the new approach.
I am honored you would offer me commit rights. I will contact you off list
for more information.
About the animations, I do have a prototype of it, and it works even on my
EeePC, however Ryan May and I are still working out some issues
(particularly with rotating and zooming).
Thanks,
Ben Root
