Can you send your script over? I think that could be just that too small
is applied or it changes very fast, so that you visually don't see any
movement.

It is not an engine, just a function that does the interpolation (ok,
admittedly it shouldn't be in DeusExMachina directory...). There is no
such thing as DeusExMachina('LinearInterpolate',...), what would it
interpolate (force? rotation? mass?).

Checkout r1741 from svn, and see scripts/test/interpolating-force.py and
run it. It should give you an idea.

I created InterpolatingDirectedForceEngine based on the assumption that
the direction of the force doesn't change (whence "Directed" in the
name), I hope I got right what you needed.
