Effect

Ripple waves across the image from a chosen origin.
Ripple distortions imitate water and shockwaves expanding from a point. Physics engines and classic filter packs both offer versions; the eye reads them instantly as disturbance.
Wavelength and amplitude set calm pond versus dropped stone.
