Hi,
I have one question:
Any idea why the particles are converted to blobs by Andreas?

Just a point to add, Peter and I continue the mail/news-mixed
conversation:

Calculations like these can be done with octave.

It's GPL (Peter, you can drop the price of Matlab) and a Matlab clone.
Nice features:
Vectorisation of almost any operation. You can do the integration of one
timestep for all particles at a time, for example.
Nice as well is the vectorized sprintf. It gives you a formatted output
as often as your input suffices. A one-liner just to convert all
particles to blobs.
So much hype is enough...

Axel
