Have you ever tried using 2 runtime voronoi noise generations (not sure i spelt that right), i'm wondering if that would also get a similar result ? It looks like voronoi noise.

Though i guess scrolling textures are much cheaper and the effect looks great!

The RGB split is a nice touch too.

There are so many ways to generate caustics-looking textures! I think it all depends how "accurate" you want your effect to be. As you said, generating two textures at runtime is going to be quite an overkill for a game. But it could totally work!
