A new TIPSY file viewer, request for comments

hallo!

As part of my semester thesis at the Institute of Theoretical Physics
(I am computer science student at ETH Zuerich) I wrote a visualization
tool for TIPSY files on Linux.

The program can run on one or many processors (using the MPI library)
and can be found at http://hubble.sourceforge.net
The rotation of the model was done using an exercise from the graphics
course.
The feature I am most proud is that by right clicking with the mouse,
the model centers in x, y and z direction, where z is the coordinate
of the particle with maximum density.
The program features 10 color maps, an edge detection filter and three
plot modes: maximum density, nearest particle and estimation along
line of sight (the last one is used if the densities are missing).
The "projection and clipping" step can be optimized for AMD or Intel
architectures.

I'd like to know if it is already usable, or if I should put
additional
effort on it (although I am a little bit tired of it).
thank you for your comments (and maybe help, it's Open Source :-)
