Its hard to tell, but my guess is that they animated the arrows along paths in a 3d app. The globe appears to have been done in a 3d app as well. Also if you notice it seems as though the arrows in a few instances seem to go off the edge as though they were rendered at a narrower resolution than the main 4:3 workspace. This also makes me think that it was done in 3d and rendered. I don’t know flash though so I suppose it could still be flash.
Hope this helps.
