Anyone have a suggestion for creating a realistic dust devil (those small
tornados that blow around trash and leaves in alleyways)?

I made a very good shape in sPatch but textureing it too look like it has
spinning particals in it has proven to be less than successful.  Here is
what I tried to use.

object{devil
        hollow on
       scale 1.02
       texture {
    pigment { rgbf <0.98, 1.0, 0.99, 0.75> }
    finish {
        ambient 0.1
        diffuse 0.01
        reflection .001
        ior 3
        specular .001
        roughness 9
    }
}normal {waves 0.5 scale 0.01 translate y*-50}}

If you replace devil with a warped cone you can get an idea of the effect I
got.

Any help prior to the 29th (wonder why?) would be appreacieated?

Thanks,
