this is a very cool physics phenomenon. i just became aware of this.
when light falls through a rippled surface, such as waves on the water, the light rays get refracted in different directions.
if these rays then meet, they make a very bright area. which is what we can see in the video, at the sea floor.
here's some more pics:

Caustics look cool. It was one of the first effects I learned when I did an internship for 3d modelling.
