caustics
Patterns of light projected onto a surface by light rays reflected off or refracted through another object. These can be seen on underwater surfaces, when light passes through materials like water, glass, and the like.
The bright ripples you can see on the bottom of a pool or on things close to it on a sunny day are this.
