Thank you for your reply. Your example is very close, but not not quite what I'm looking for. I'd like those arrows to move along the path, while the body of the arrow morphs to the shape of the map. Everything I've seen is a single element moving along the path, but not changing shape. Maybe the best way to describe it would be an animated dashed line along a path, but the each dash has a chevron or triangle on the tip of it.
