Here's a little something I wipped up after watching Toy Story 2 (which was
only recently, because of my trip). I was inspired by the dusty shelf scene,
where Woody finds Wheezy the penguin. Awesome stuff they're doing there: no
particle simulations here, that stuff was pure geometry. For my own work I
used media. What do you think? What can I do to make it better?

I can tell what you're trying to do there I think, except it almost seems to
be more like a blurred picture instead.  Perhaps more ganularity is needed?
I noticed in the movie that it seemed a little more like very tiny fuzzy
clumps instead of dust particles.

I have not seen the movie either but the dust for one should appear to sit on
the ball not the appearance, here it looks like the dust is part of the ball ,
maybe another very clear ball w/ a _map of some kind... media is a good
direction... good luck...

Oh... The dust would kill the reflection yes??

Is the atmosphere itself supposed to be dusty, or is dust to be settled on
the ball and/or floor or both? i havn't seen the movie yet.

Tiny toy footprints would do the trick. Just model a foot, make it invisible
and place copies of it in a pattern that makes it look like something has
walked through the dust. That would force the image to look like dust and not a
focal blur of some sort.

Here's the original scene, on which I based my own. I took it from the
November 1999 "Computer Graphics World" magazine, page 32. Of course, it
looks much better in the magazine than it does after scanning, so I don't
know how well you can use this to compare it to my work.

To answer your questions:

Ryan:

The dust around the ball is indeed media. What you're seeing is a spherical
density, which goes from rgb 0 to a planar density which is translated to
the top of the ball, and goes from rgb 0 to bumps. Around the ball itself I
placed a slightly (R*1.01) larger one that is pure texture to help bring out
the dusty look (because the media is too transparent and fuzzy). I also used
this trick on the floor. I have not tested this to see if it kills
reflections, because it renders very slowly as-is.

Bob:

The dust in the movie was indeed made up of 2.4 million particles, including
hairs, dust bunnies, spheres and flecks. I used media, and agree with you on
the blurred look. :( I'll have to work on it.

Ross:

The top of the ball and the shelf itself are supposed to be the dusty
objects, there should be no atmospheric dust.

Josh:

I actually made a small hole in the media right where the ball is, so you
can see that the dust only accumulated on top of it. My intent was only to
replicate the dusty look and not to make a "Toy Story" world, with living
toys walking around. I could maybe do this in the future.

Not much.  Maybe put some books up there.  Great idea!

When I saw the dusty scene in TS2, I knew immediately a good way to simulate the
rested particles. It would not work for floating ones, however. You can use the
trace function to shoot rays at the sphere, and place very tiny transluscent
sphere only where the rays intersect the ball (or whatever object you wish to
use). Of course you would have to use the Superpatch, and then learn (to some
degree) how to use the trace function. It is actually one of the projects I
intend on doing in the future.

Maybe a spot where the dust has been disturbed, like a finger smuge, showing
what the shelf really looks like.  The dust on the ball is apparent, but the
self needs some contrast between clean and dusty...
