Actually not a ball at all, this is a bunch of photons projected onto
a flat 'screen', using dispersion.  Not very realistic (high
dispersion/low dispersion_samples) but pretty nontheless (I think)

Render time was around 11mins on my 1.4ghz Athlon, with +A0.1 +AM2
(approx 8.5 million stored photons)

What's the code, I'm curious...

Wow!  Neat ...

I can't think of a single thing I would change about it.

Looks great.

Quite simple really, a spotlight shone through a thin 'glass' box onto
a white plane with 0 ambient, and then you just play with the normals
on the glass box.

I've posted the source in p.t.s-f

interesting :))

I get simmilar effect using media, and simmilar image is also in example 
scenes (using afair crackle as density)

Hmm... halve the resolution, and reduce the number of photons to the minimum
required to look ok, and render an animation overnight while translating the
normal texture through the plane... that'd be neat =)
