We will share the code when we get it to the point we are 100% happy with it. (Or 95% anyway)
I'm still developing it in Shake, and then the other guys are doing it in AVISynth, we will end up trying to get the two code bases synchronised to get the same effect, or at least as close as possible. At that point we will release the scripts to the masses for use in whatever.
It is fun inventing new ways of processing images for the project, it is throwing up challenges that I don't really get in my day job - restoration is a different kettle of fish to production, but the required skills are similar I guess.
So the stuff we are developing here will probably end up being useful in some form in production anyway.
The starfield thing was one of those 2am ideas that we weren't sure would fly, and it was immensely satisfying when the stars popped back into existence after the first code run!
