I thought it's not even near of finishing, but I guessed that you'd want
visions of the image (I would've). My apologies, if I was so wrong.

Ah. For my eye, it looked like a stone for my eye. But after all, I
didn't even realize that those cracks exist (thou it's logical, while
thinking it now).

Nice! Now, even I can see (and understand) what's the underwater part
about :).

Pillow should be better than cushion.

Yup that's exactly what I mean! I found a good reference site:
http://www.pmel.noaa.gov/vents/nemo/explorer/concepts/pillows.html

There's an awesome video at the bottom of that page, makes me wish I was 
doing an animation!

It is doing that already but the effect's too subtle so it just looks like 
lighting, I'll crank it up a bit :)

That's the case for ones I've seen.


A few pictures I took in Hawaii

    http://www.geocities.com/ramayer/pics/smoke2.jpg

And the steam glows really cool at night:

You also get really cool cracks in the ground where the Lava shows
through the rocks.
    http://www.geocities.com/ramayer/pics/lavaeyes.jpg
Such cracks might look cool in the foreground.


(sorry for the links to pics; but I can't render anything that cool)

> I rephrase: in the videos I've seen, that's how it looks.

Yeah, that's what it looks like in real life.
