I found this to be the fastest way to create really cool caustics for underwater scenes or pool scenes.
This technique could definitely be extrapolated to create underwater logo intros as well. In a future video, I'll convert this into a single node that can be added to any existing material to convert it into an underwater material.
The base of this video was inspired by Polyjford's discovering ake caustics in blender video, but that works only in cycles and is far more time-consuming when rendering. If you have a powerful computer and enjoy using Cycles, do check out his video over here:

If you have any queries, questions, or suggestions, comment below and I'll respond as soon as I can!
More sci-fi animations, wallpapers, loops, motion graphics, etc. using blender3D or other completely open-source free software will be coming soon! Stay tuned!
