Very strange looking thing indeed. How did this sinkihole originate? Well, the scientists are not sure. That leaves some space for speculation and inspiration. Here is my impression. The painting is called The Meeting/Seizure at Sao Paolo (Reprise of Guatemala). The part of Sao Paolo came from the recollection how the buildings looked when seen from the window of an airplane. Gold and silver paint worked well with the thrusters/beam/ray.
