For the "Hollywood graphics" shown in various talks about the LCLS X-ray laser nanocrystal work, I generated something very similar to what you want. To do it, I wrote a program which ate a list of reflections and wrote a script for Persistence of Vision (raytracer), then invoked the raytracer in "animation mode" to make individual frames of animation before using a video encoding program (mencoder or Final Cut Pro) to stich them together. It was all a bit hacky, and it's a terrible way to visualise results for anything other than impressing audiences, but it did work. The code to do it is in our FEL crystallography suite which will be released publicly quite soon. Customising the animation is done by editing the source code, and isn't easy. For something a few years ago, I wrote a different program which, amongst many other things, showed a 3D reciprocal lattice weighted exactly how you describe and allowed you to roll it around and zoom in and out. If it sounds useful, I could resurrect that old code and tidy it up a bit to make it useful - there's not much to it. It could be useful for my own work, so I could prioritise it a little higher if it could be useful to other people...? Tom
