Gravity
A starfield lensed by a mass that rides the pointer
A starfield behind a heavy mass: the stars smear into arcs around it, a bright ring stands at the lensing radius, and images double inside that ring. Dragging the pointer drags the whole distortion across the sky.
Rendering cost: medium. A few dozen samples per pixel: comfortable fullscreen on a discrete GPU, but cap the pixel ratio for a retina hero. How to tune it
