Now that Sinus has gone GEGL it has become a lot more fun.

Not bad, but you have little control on the shape, you have to click "New seed" until you get something you like.

Nice. How did you distort the text to match the waves?

Displacement map

I made this a long time ago. Its 50% inspired by the caustic lighteffects in Blade Runner 2049 and the other 50% by a Photoshop tutorial for text in a swimmingpool.
It was originally for a tutorial but for some reason i discarded the idea.

Used the same technique for the caustics as you did. Colouring with a layermask, though, not with a gradientmap.
Plus some more trickery.
