Following @themos post about the The Black hole accretion code , I have contacted someone of their team (O. Porth) who kindly accepted to post in Wikimedia (license CC BY-SA 4.0) a beautiful Fortran simulation of the accretion around a black hole:
I have put it in the French and English Fortran Wikipedia pages as an illustration of Fortran applications:

I plan also to ask permission to the author of those ocean simulations to upload its velocity field picture (bottom of the page) in Wikimedia (CC BY 4.0):
https://www.nemo-ocean.eu/gallery/
Maybe those pictures could also be used in Fortran-lang.org?
Let me know if you have or find other Fortran simulation visualizations under free license that could be uploaded in Wikimedia. Let’s rejuvenate the imagery of Fortran.
