It's a nice pic, but... Why would it form a torus in outer space, shouldn't
everything be nice and spherical? Well I don't really know what I'm talking
about tho

yer right in theory, however if the object was spinning it would form the disk
due to some nice physics

Yep. I forgot about the "coliding particle spin factor". But sci-fi explosions
should be spherical and they aren't! Hrmph!

Why ? Assuming an object at rest with a uniform shell, and a way to ignite
the exploives it contained in a uniform manner perhaps it might appear as
a spherical blast. Given that the container may have different thicknesses
and the explosives my ignite non-unifomrly, and the whole container may
not be at rest, then it is safe to assume that you will not get a spherical
detonation.
It's all in the engineering - as a previous employeer of mine was fond of
saying.

I see. Actually I worded that entirely wrong, I was thinking more along the lines of
Star Trek "collapsing stars". Those should be, right?

Nope, stars spin (at different rates for different lattitudes) hence (due to
physics that I have forgotten) the explosion will not be uniform.
Think of ring nebulae caused by collapsing red giants.

It's always just unfortunate for those poor souls that they can never figure out
how to escape a toroidal explosion. The best part of the Wing Commander movie was
due solely to my friend's comment whilst the heroine was desperately trying to
outrace the wavefront of a large explosion:
[groan] "Fly..... up. Up!" "Obviously common sense isn't a requirement for
space fighter pilots."

2D thinkers all the way.

ok you physics bums if the fuel was a sphere and it was spinning at high speed the
equator's particles would be moving faster and have a higher outer force and the ones
up north would have almost no force therefor the northern ones would go up due to the
blast and the equatorial ones out but with more force forming the shape of the
explosion i have made. but not to necessarily the same extent and not with a nice blue
ring :) now that you've all had your basic particle phisics for the day check out the
animation in p.b.a :)

But there was no sound!!
If I can be serious for a moment (hrm), there's so many dynamic processes at
work in such things it wouldn't be plausible to say there's one specific way for
sure. Well, obviously, with the various large scale explosions such as from
novae there's plenty of variation to be seen, as Gail S. had mentioned about
those kinds of nebulae.
There had been a test using barium in a space explosion to track it's plume in
the solar wind and Earths magnetic field, was done several years ago. That
would be interesting to see a closeup picture from the moment just after it
happened.
