My render don't look even remotely like your image, and I didn't change 
anything.

Alain,

did you render with the last sphere option?

Haha, no, more a "Bob Ross Happy Accident". Just going beyond sensible with
scaling of blobs and I guess then you run into numerical problems.

Thanks, will have a look ...
Btw, Roger Dean also have real time online lessons on his Facebook page.

Rather interesting object, will play with it. Reminds my fractals 
experiments at 90-x.

It looks like we are on the way to the modern art gallery.
I call this artwork "Spring in NY", guess it will be sold
for about $1.5-1.8 millions and I will by Meta Quest 3 then ...

Hey - this is a really good one.
It looks like a white blood cell from Asimov's _Fantastic Voyage_!

Could you share how you achieved this result?
This looks like a good base for future modeling.

Maybe you should try using emission to see if you can get some nice "glow"
effects.

I could also envision giving it a green hue to simulate some sort of microscopic
plant cell, and maybe a (mostly) clear/ior internal region with some irregular
"organelles" to make it look like one of those microscope slide images.

Horton hears a who?   :)
