Some nice new videos on Path Planning

So, recently there have been a couple of new videos that illustrate ‘new’ techniques in path planning and especially crowd simulation for games. The first is on so called flow fields in supreme commander.

And the second is on path planning in the upcoming Starcraft 2; I don’t really know much about the techniques used here, but it looks as if they combine local force methods with A*. It looks cool but again the behavior of the zerglings sometimes is a bit unnatural still, some odd patterns can be seen when the units are packed together:
