heh, you missed CSV, AA, _and_ p.b.a.  :-)

not too sure yet, need to look this over, thanks for the ref.  from my
lack-of-know-how perspective, roughly, I think of two circles, both approx
around origin, the smaller for the look_at, a larger for the location; the
larger more (shallow) helix, ie I would like from clock 0 to 1 for both
diameters to slowly increase, and the location to "lift", so that the effect is
like zooming out, taking in more + more of the plane.  thinking the movement
should be clockwise (while the spiral gets drawn counter-clockwise).  anyway,
near the end one should have a "bird's eye" view of the spiral.  (I'm reasonably
sure it's not very difficult, but you know of .. my limitations :-))

regards, jr.
