Very convincing, Sam!
It was generated by Pov code or with an external program?

Thanks for seeing past the bland scene settings :) It would look much
nicer set against a partly cloudy summer sky...

It's 100% POV :)
Around the same time I was trying to use SurfaceEvolver to manipulate
meshes. SE makes really great minimal surfaces, but it's very difficult
to generate meshes it can read... I never got very far :(
So I think I'll stick to using blobs, which are are easier to code and
faster to render. Hopefully I can make some improvements on the setup
soon...

Thanks, I might just do that. I've got an account set up, I just need to
throw some images at it.

It 's neer perfection but just one subjestion:
Your bubbles seems to me bit too regular, i suggest to rotate in x,y and z
randomly, and scale each randomly of 5% par exemple

Any X or Z rotation would be unrealistic. Then, a Y rotation would be
prety useless.
I don't see why scaling them randomly would help...
The perceived regularity is just an illusion as your brain always work
VERY hard and effeciently to find patterns, or create patterns where
there are none. That's why we have constellations and you can recognise
objects and creatures in a cloud.

Randomized rotation and scaling might help a little, though a better
solution would be to have two or more blob components per bubble and
then translate them randomly in relation to each other. I'll give it a
try at the next iteration, thanks!
