Inspired by the reflective pics, and a diagram in my Chemistry text, I
made this little pic of a NaCl crystal dissolving in water.

It's not perfect, but at a render time of about 3 hours, I didn't feel
like making too many changes. I'm using an 800x600 version as my desktop
wallpaper. Not too imposing, and blends in well.

Neat-o, I'm somewhat of a chemistry fan.  Looks like the Chlorine atom is
getting carried away by the H2O (um, yeah, it is, that's right...).  Off
hand I wouldn't think of Sodium as being a lighter element, I had to look at
the Periodic Table to confirm I was right.  Long time since I had chemistry
class.

Actually, there is both a chlorine atom and a sodium atom being carried away.
The other (Sodium, I think) is in the foreground, and is a bit too blurry to
really make out. It is the one being attracted by the O in the water, rather
than the H.

I based the image on a diagram in the text, colours and all. I don't know how
accurate it is...

Nice image! The focal blur is a nice touch, I should learn to use it.
Having fun in chemistry?

This is very nice, especially the focal blur, i think you may have the
making of a cool litestep theme here :)

Will it explode? No? Well that's no fun <sigh>...
I've carefully forgotten everything I ever knew about chemistry, so I can't
really comment on the accuracy. Is an oxygen atom really red and shiny? :)

Heh, I always imagine hydrogen as red and oxygen as white.  Preconditioning
by earlier Bohr models perhaps?  I too have been away from it too long to
say.

3 hours? What kind of machine are you running? Or is there any advanced
quirks to the code I don't know. Just curious.

Some two hundred spheres can be done in a couple of minutes, can't they?

But I love the image! Perfect sphere-image; I have this fascination for
them; maybe because I cannot model anything else... :/

Average pentium type computer (I'm ashgamed to admit I don't know the stats.
Waah!)

The 3 hours comes from a 10x10 area light, and a focal vlur with 100
samples.

Plus, there are about ten times as many spheres as are visible. Most of the
distant water got lost in the blur.

	I'd guess it's the focal blur that slows it down...
