When I read Sam's post, I thought "coyote scat" was an algorithm that I 
hadn't hear of yet.  Now, reading your reply, I realize what he is 
referring to.  Duh.  :D

BTW, nice work Sam!

the famous coyote scattering model for media ;)

Well, I guess it's more an algorithm for distributing objects randomly on an
infinite plain... :P

That sounds like a fun show to listen to. Where might I find it?

Yes, dead grass would make it look better. More soil showing would also 
help. The water idea is good, but too much iridescence on the water's 
surface could give the impression of an oil spill :S

Ah, come on, it's fun! Gotta hop on the tops of the rocks. Can't fall 
into the deadly green lava :)

Yeah, there are many more things to use them for. It would be great if 
POV had a proximity pattern built-in, like older versions of Mega-POV did.

Yeah, animal life of some kind. Something without hair, until somebody 
comes up with a quick and easy hair macro :)

Most snakes will typically slink through the grass if it's there, which 
means I would have to make the grass bend... which isn't outside of the 
realm of possibility, but it might prove very difficult :(

Just a basic green texture for now. No scattering effects, apart from 
the area_light and radiosity for the scene, and the double_illuminate I 
gave the grass.

You're trying to make this an epic (read: long) render, aren't you? 
Might as well add photons and dispersion while I'm at it. Focal blur 
doesn't hurt... well you know the litany :)

Given up on it, have you? ;)

Nope, it should be easy. Just a few more triangles...

It would look nice, but to make it look truly good would take a *lot* of 
work to get all the drops to act as if they are riding the grass hairs :/

Scat is interesting stuff. You get an idea of what the animal ate. I 
once saw coyote scat with prickly pear berry seeds in it. If you don't 
already know, prickly pears are cacti, and the berries have many thorns 
on them. Prickly pears have both large and fine thorns, and the small 
ones do not come out easily. Coyotes are desperate creatures.
