Recently, while helping a buddy with construction work on his house, I was working with a concrete mixer. I threw one shovelful of sand and cement after another into the concrete mixer and I was quickly getting bored with this type of monotonous work. Then I suddenly had a daydream. The concrete mixer became an alien space harbour in my imagination and the grains of sand became spaceships which wanted to dock in the harbour to do business there. So it might well be that my spaceport reminds you a little of a concrete mixer. I modelled the scene in Blender and made a finished picture from it in GIMP.
