...well, not really, just red paint.
This is a quick test with a particles system I'm writing these days. This
still doesn't look that good, but I'm going to post the animated version
ASAP (tough you can find my previous test in p.b-a).
Comments and suggestions are welcome.

hmmm...

....chunky....

More small particles? ... like a LOT more ?

To say the true the particles are really small. Look at the smallest
particles on the ground and consider that all the particles have same
size...
The problem here could be that I used only 100 iterations, with 40 particles
per iteration... just 2 minutes of parsing.

It reminds of the way liquid behaves in a zero G environment.  It holds a
globular shape as opposed to a flattened stream with gravity.  Paint in
Space?

Blood is more translucent though. Something like that glass of milk...

I'm intrigued. How does your system work ?
I've done some thinking but all solution I came up
with are computational monsters. Especially with
Povray, the language isn't quite as powerful as one
could wish to do real computations and animations...

Best,

Computational monsters? It's not the case.
I'm not a programmer neither a physicist, so I have no idea how particles
systems are usually done... ;)
Mine uses a simple 30-40 lines code to do all the calculations. It took me
just 30 minutes to write it down one or two weeks ago. No fancy features, no
inter-particle interaction. Yet it seems to work well in animations. And SDL
is required for trace(). I will post this scene animated tomorrow.

Neither am I. But, I don't know... I would have particle glue together under
a certain treshold of energy difference, repulse each other when compressed...
Glue to objects, etc.

That type of physical constraints.
