Make me a gravity engine. This image is a lake in which you can see starting from the perspective of underwater on the bottom half, with the surface of the water visible near 1/3 of the way up from the bottom. In the water is and alien engine in the shape of a three dimensional diamond. Above the engine is three rings starting from largest to smallest at an even spacing between each other made of water. Beneath the surface of the water, it is visible that almost in reflection, rings of water are missing. The three dimensional diamond must be halfway in the water as if to show symmetry like the rings of water. This must have a realist look to it. Essentially this engine is pulling rings from underwater and suspending it above it. I also want the lake to be beautiful and in a valley with mountains visible in the background. I want a big visual contrast between the technology and nature. I want the engine to feel ominous and unwelcoming.
