The things that are "in the works" right now:

• Creating VRML movies. Check out this example (VRML movie, requires VRML player, for example http://www.parallelgraphics.com/products/cortona/):

• Expansion of arbitrary dynamics onto the spatial spectrum of eigenmodes - done
  
• Krylov-based algorithms for greatly improved performance of computing eigenvalues - done

In the more distant future:

• Runge-Kutta is going to be replaced with a geomtric integrator (I have already done some work on this, but it is not going as smooth as I would like it to).
• The program will be completely parallelized to effectively work on clusters, using Intel cluster solutions.

If you like the ideas, please e-mail me at mailto:rivkin@rkmag.com. I would love to hear your suggestions, or at least to get in touch with you so I can make you aware when the new version will be ready
