I am solving (sort of) equation of motions which take some time to evaluate. Now I would like to see my test particles and the associated values like velocity and acceleration etc. evolve on the screen in real time. After each step of the integration routine, I would like to update a GrapphicsArray such that only the new values are added to the already existing graphics and not a completely new window with a completely new graphic has to be created again. Updating a Mathematica -Graphic- object is no problem. However, displaying the PostScipt output on the screen is a problem. Currently you would end up with your screen filled with hundreds of individual windows (one window for each step) each differing by one dot. To use the animation software you have to calculate all dots first and then you can display them. But this makes no sense in my case. Especially in the test phase I want to have a direct (visual) control of what the calculation yields - during the calculation, besides looking at an annoying table of numbers scrolling over the screen. Does anybody know a way to get such an effect (for Open-Windows on a Sparc 2), or do I have to wait for Mathematica 5.2 (or 4.1 or 17.5 or so)? Heino Falcke
