[confusion of cancelled messages]  ;-)

The slow motion shows me that the ball does not hit head on... So, all 
is well (except for the poor guy who painstakingly built that tower).

Ctrl + Z works wonders.

Here's a slower version, with radiosity. The camera tracking was easier than I
expected - I added some pre_sdl in the BPP lua to #declare all the exported
items, putting the bricks into an array. I could then calculate the average
brick position for each frame, and use this location in the camera look_at. This
opens up all sorts of interesting possibilities for wacky tracking shots -
following individual items closely, even 'attaching' the camera to items.

I will experiment further :)

Better and better. Looking forward to some spectacular pixar scenes ;-)

Um, what? Povray can do this now?  Wow.
