You may have missed some of my earlier emails on this... I'm calling
python from a C dll so I can play with vis plugins for Sonique in
Python. So I can't change that aspect of the implementation. Python
interprets the buffer object as a long string.

Unless there is a way to convert from string to 2d array, then back
again? (Ideally without copying the whole thing and copying it back -
doing that would send framerates down the drain, I'm guessing)

I will try to post my code on my website in the next few days.
