This started with a look at the microwave antenna on the radome platform. When I recreated it on a larger scale and added the warning lights, it morphed into a crater creature. The cratered surface is a noise-filled layer subjected to the render>lighting effects filter -- the craters are the effect of masking the surface with Eye Candy water drops and applying an emboss layer style. The planet surface was bent using the distort>shear filter and the overall look comes from the poster edges filter.
