I would like to be able to do real-time visualizations of my paint scenes. I
don't know of any game engine does blobs or metaballs, but maybe some-one here
knows of something that could do the job.

I don't know of any game engine that does it, but you will find some 
examples of real-time metaballs on shadertoy.com eg:

https://www.shadertoy.com/view/ld2GRz

I don't know exactly what type of data you want to visualise, but you 
might be able to edit the script (that one is fairly straightforward to 
see how it's moving the blobs) to show your data instead.

IIRC shadertoy is only online. These days I reach my cap very quickly  
since everyone uses youtube and now I am already throttled again. My  
normal connection is between 4-10Mbps. When I'm throttled it's down to  
300Kbps.

I'm not sure if you can just save the page and run it locally. It might 
need some tweaks. But in the end shadertoy is just a friendly front-end 
to webGL. The shader code should be copy&pastable into a local webGL page.

I just love it when shadertoy crashes my computer :(

Think the term that should be looked for is.. "voxel"? I know that they 
opted to use them for the new Everquest Next. And a quick google shows..

Voxel Farm - not sure this is an engine, or a service.
http://www.atomontage.com/ - Think its an engine, from a quick look.
http://www.blackvoxel.com/ - definitely an engine, except, it looks like 
its more minecraft (i.e., doesn't employ smoothing of geometry).

Think that is the major issue with these engines. Some support 
smoothing, which is to say, they function as metaballs, and others just 
do blocks, like minecraft. :p The first two above look to be "smoothed".

Looking for "voxel engine smooth" tends to net just terrain, not 
objects, sadly...

All voxels seem to be cubes. I came across this though. I'm still trying  
to wrap my head around it:

It would be nice if Rune could add Blobs to Unity3d :)

Well, can't argue against the "cube" thing, but, like I said, EQ Next 
Landmark uses voxels, and every "except" the trees, and characters in 
these images is "voxel data". So, guess they worked out some way to do 
it. :p

Good example in fact, sort of "before and after" smoothing them:
