My example is simmed, but if you need it for animation, You have to store it somewhere permanent, such as in a cache and read it back, Once, partly for fun, I actually stored it in geometry. I made a disc that read a scalar value to drive the Y value as it spun and baked the final simmed geom, then used that y value around the disc as a cache to read from and it worked fine. In fact I used it to store the animation for a whole character. Similar to what a record player does for music. I found it amusing that I could just load in some geometry, and the shape of it contained animation that could drive a character. Going off topic a bit, I also once stored the rgb amounts of a video per frame as a geometry point cache.that could be loaded back and deciphered by ice to recreate the video. It worked perfectly. I even toyed with the idea of making a geometry-based 'video codec' but then realised i had real work to get on with.
