It wasn't intended... or at least not that tight a turn. I left it in
because it did look like a sudden avoidance. I think it's too fast though.
The spline for camera position starts at 0.1*x and only goes to 0.125*x at
0.1*clock then moves (well, cubic splines) to 0.5*x at 0.225*clock. It's
just a kink in the spline path at that point apparently. The last few
points are similar to the first few but looks very different. Goes back
from -0.5*x at 0.775*clock to -0.2*x at 0.9*clock (both are a 0.125*clock
separation in time) and finally ending at -0.05*x so it's the 0.075*x amount
difference near the start and end parts of the spline along with a
straighter beginning than end making it look so much unalike.
Really a very simple spline path.

The sexiest phrase uttered in any computer game ever.

I *was* wondering what povray on that tool could do. How about this?
Real time rendering of an Imax-sized screen of this flyby? Or at least, such an
Imax theatre project with heightfields would come closer to needing the full
resources of the ASCI tool than a version based on isosurfaces.

It should only be used against terrorist nations. (But then again, targetting
civilian populations is --- nevermind....)

And I'm looking forward to the day when such things will be possible to do
at home ;-)
About 10 years from now perhaps?
