Yes, but that can be already done with a few scripting work 
You also made me realize than scripting this filter can also generate cool illumination animations.

I’ve added an interactive preview module in the filter Illuminate 2d shape: it is now more easy to get an idea on how the estimated normal map behaves for different light directions.
Could choose here the position of the light
- Wow cool.
- Why do you need a second preview window. Can’t you add it to the normal preview window?
- It would be very useful to have such a preview in the “3D elevation” filter too.
No, the G’MIC core has no control over the Qt-widgets used by the plug-in, that’s why it manages its own window. This way, the filter interactive preview can run also in the GTK plug-in, as well as from the command line.
Maybe one day, at least if someone is willing to contribute ![]()
Nothing short of wow. Enjoyed the video, David. 
This animation reminds me of the introductory shot of the adult Magneto moving the old German coin between his fingers in the movie X Men First Class.
@bazza Interesting but the illumination is a bit twitchy. 
@afre Yes. But it work better of what thought
That is pretty cool. Since less and less cartoons, animes and 2.5d games (and of course more technical applications but I love 2d entertainment
) are being worked on by hand, this type of research is a big step in making them more streamlined and natural.
Hope the artists get more respect though. At least for animes, there are stories of employees being locked in their office until they finish, paid dirt salaries and therefore have no personal time with family and friends and for leisure.

Dust shaded with 2d-ilumination 
Really cool, Bazza.
