Yes, those were my thoughts and hers too.  It will be done ASAP.

That will have to wait.  Leila was the first student at our labs to use
VTK for FEM, but she's defending and leaving this month.  I myself don't
do any FEM work.  Hopefully someone will pick up where she left off,
she also wrote some nice code for improving mesh quality that her
supervisor might eventually agree to release.

This is also a good idea.  The class was originally written for VTK 3.2.
