Computer generated 3D abstract forms.\n\nNote: This image is less than one year old, and is  not available for use anywhere else. I created it on Blender 3.0.1,  and that is the reason it has no EXIF data. I uploaded in a property release section a screenshot of processing the composition on Blender on my PC. Date of creation is 01/11/2022.
