PyCC can visualize without writing to file, if the user wishes. We utilize the
vtkVoidArray class for sending the contents of Numeric arrays directly to the
graphics card.  Additionally, plotter can write the frames to file as either
vtk files or png graphics.

Actually, the plotter does not depend on the DOLFIN mesh at all. We have a
seperate class MeshLister, that can be built from a DOLFIN mesh, that provides
the data needed in plotter to do runtime visualization in VTK.

Please, go ahead and use the code in DOLFIN if you want to. We can give you a
GPLed version of the file.
