"Sideral" is archaic for "sidereal" and it means: emanating from the stars and especially from stars held to be malefic. Sideral Wind is an interstellar force that comes from evil celestial worlds and that can take the form of strong thunderstorms hitting and sweeping any planet in its way or generating alien bodies in the sky.

This is my first work that produces SVG output. I did have to adapt my stile but, hopefully, I did not move too much from some other stuff that I have been making in the past. I will keep studying because I see a lot of potential in the technique. All holders of this project will be allowed to an access list in my next one.

As always:
- three modes Light, Dark and the Gold one
- hit 's' and save the svg file at the current resolution of display
- hit 'p' and save the png file at 3072px x 3072px
