Here's a little more wanton destruction for you all. I must profess to be a
little concerned at the eagerness for more of these pictures fro some of
you! ;)

Bill, very nice... is this a macro? And is there any physics?
if yes, can you share ?
Regards.

Good work, but those images cry for motion blur!

I keep looking for a bullet streaking across the screen. :)

Must be our caveman ancestry. ;-)
Really liking what you've done. Was wondering if gravity was part of the
set-up? (Or maybe I'm just not noticing its effects.)
More! More! Bash! Destroy!

BTW, I've been working on an explosion of my own (heh heh.) With
media-sphere dust trails. Not quite ready yet, but I'll post when done.
Let's see...looking at your image, and venturing a *guess* as to the basics
of how it's done, I would say...
the bricks are all moving in the "+cannonball" direction according to how
near they are to the cannonball-travel axis...closer means more movement.
(Random, of course.) And they fan out in a cone shape, each stone's random
distance in those two directions depending on how far each is from the
center(?) of the castle cylinder (or perhaps from the point of entry.)
So...am I triumphantly crossing the drawbridge toward the gate, or am I
still on the other side of the moat?

That's quite a lot of debris.
Have you tried your code, when there already exists a hole (like a window
hole) in your tower? And if so, how does it look then?

The macro simply defines a translation as a function of how close a given
point is to a straight line (the 'bullet' trajectory). This translation is
calculated and applied to bricks as they are generated when building the
chimney. There is no physics, but as Mike Williams pointed out, there could
easily be with only slight modifications. I'll try to make it more friendly
before sharing...

Exactly right.

Not quite. Each brick starts at its correct position within the tower. Their
movement along the cannonball axis is calculated as a function of their
distance from the axis - it's a one-off translation, no time-factor is
used. Two random vector components orthogonal to the cannonball axis are
scaled with the distance to produce the fanning-out effect. As mentioned
before, there is no gravity.
Smoke and mirrors!
