The most powerful feature of this software will be to visualize the geodesic motion of particles and objects in any space-time. And of course the ability to watch a whole dust cloud move in geodesic motion.
Some changes that we would like to make is to make this software more independent. Utilizing java may be the key to this. The multi particle routine will need to be implemented in some other way but for single particle the java language would be ideal. In order to do this however, we will need to do numerical differentiation instead of analytic and thus we will see errors introduced. But, we are confident that we can keep those to a minimum.
