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...

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.

That would be easy to implement but really slow in animation... (a loop
which checks the distances between every particle would do the trick).
This is *simulated* with little random amounts here.

When the work is finished I'll post the code. Now it really needs to be
cleaned up.

Just wash the ax off when you're done. Oh, and you forgot to lock the
door, so look out for Lizaveta.

Why bother? I'm not interesting.
