I believe that Andreas has updated a function that would help in
this regard called "tween", I think<br>
<br>
Unaware of that, I built a rather complex animation tool. You can
see a temporary example at
<a class="moz-txt-link-freetext" href="http://track.pacificcup.org/track.php?race=transpac">http://track.pacificcup.org/track.php?race=transpac</a><br>
<br>
Select a boat from the left of the screen and then use the vcr
controls at the top to animate.<br>
<br>
It works by maintaining an array of points that parallels the points
in the linestring. At selected intervals, I add a point from the
array to the linestring. Then I clear the linestring at the end.<br>
<br>
To do fancier stuff, like go in reverse, I added a time attribute to
each point, so I can count backwards through the vertices (points)
of the linestring till I get to one that is older than the new
cutoff time, deleting the newer ones.<br>
<br>
The code is, well, complex, because the page is doing a bunch of
other things. I keep meaning to extract an example, and perhaps I
should! Meantime, it IS possible.<br>

<div>Does anyone have a copy of this example? I would like to know
if ti would be possible to create an effect like this using
openlayers:</div>

<div>I actually don't need the map panning or to follow driving
directions as my use case requires a generic world map with the
polylines linking major cities. A closer example would be
animated flight paths.</div>

<div>I would be extremely grateful if anyone could provide the
missing example or offer any advice on how to achieve this. I've
been playing with the cloudmade leaflet maps here:</div>

I want to animate the red line - I will need to dynamically add
lines to the map based on lat/longs and distance covered by
users)</div>
