hi,
there’s a few images.
I stareted with an old cg sphere model I made.
I opened it it 2.56 & applied the solidify modifier twice on each mesh that makes the sphere.
next I added some weird materials, duplicated one of the mesh, applied the spin modifier…
then scaled the two sphere mesh…
then added the blender edge setting & tweaked the materials for some colors.
then i deleted the sphere objects & tweaked the materials on the background object…
finally I moved & scaled the background object for a different perspective…
enjoy.
