Just wondering how one could visualise a curvature in spacetime. If anyone has a site, image or video showing this it would be appreciated.

While many have used the image of a bowling ball on a trampoline as a way to visualize spacetime curvature, I prefer to think more along the lines of a low pressure system on a weather map, with the planet/star at the centre of the low. And just like a bedsheet hanging on a clothes line is sucked into the middle of the low pressure system, objects passing by a planet are sucked into the gravitational low. The circular nature of a weather low pressure system matches exactly with the circular nature of frame dragging in spacetime.
