You're right, that when the data are changing (not jsut the view on
the data) you lose much of the benefit of OpenGL. NOne the less, you
still can get benefit, particularly in Python, from using VBOs -- that
way there is no looping in Python -- you can build a VBO from a numpy
array at the speed of C.

Display lists probably wont' help as you would still need to build up
the list -- it's also old-style and practically deprecated approach.
