I created some sci-fi interface textures (2k resolution). First I tried to create them in inkscape but I got problems with some circular shapes.(In total 4, each with / without effects)

So I used blender - xD , creating simple geometry with an emit shader. The circular shapes are created with spin and solidify modifier (I also used array and skin modifiers for some parts)

I rendered into multiple images / "layers", then "composited" in GIMP... adding some effects (like glow)

Note that the source archives are big (the GIMP files are huge, using 16 bit colors, including many layers, some with effects)
