This is a 16-frame pre-rendered water caustics animation.
Now, I know that this is an effect that can be done via shader scripts on the GPU, but not everybody knows how to do that and not everybody wants to make a game that requires a beefy GPU.
Provided are three sets of images -- the raw frames and two assembled texture atlases, one with an alpha channel and one without.
The atlas without an alpha channel is intended for use with a multiply type blend mode (forget the exact blend funcs needed but it's pretty straight forward).
Anyway, hopefully someone finds these useful.
Attribution Instructions:
I only really care if this effects texture has been useful to somebody. So... if you do use this, drop me a line if/when you have a chance!

Is it output from this program?
No. It's from an old version of the program that was open-sourced under the GPL license. The licensing terms applied to the source code and program only, not the generated output.
The fact that the authors have since closed their source and made the program commercial with different licensing terms is a moot point. I did not use their new program, I used an old, modified version under different licensing terms.
This was very useful to me, thank you sir. Karma is in the air
Thank you! I've used it to make water texture for my wargame. Looks great.
very cool. wish I found it sooner
I think it will make a few of my projects easier

Thank you! These were super useful for creating... Aurora Borealis? O_o It turns out if you use water caustic intensities as a height map, with a few ripple functions you can actually use these to create the ribbony-effects of aurora borealis! Imagine that?! I implemented this in a ray marcher and they are now part of a-starry-sky, https://github.com/Dante83/A-Starry-Sky, when the user enable aurora borealis.
Thank you for these awesome textures!

I used this as animated water for a SNES high resolution demo: ROM / Source Code
I used this for a school assignment! I don't think I can legally share the source code but I have a video of it here!
Hey! I am new to Unity and I can't figure out how to use this.
I made all the images into materials and using the animator I can get them to change but it's just black water. I can't get it to be transparent or show water under it.
Can you please help me? I don't know what I'm doing lol. I need 7 different water colors so I really don't want to make 7 sets of 16 materials.
Hello,
That is definitely a question for the unity forums. I don't use unity at all so I'm not able to help you.
Sorry.
