I'm actually watching something about this on Discovery right now.

Whenever it rains, the sand loosens. Because of the sand moving around because of the water, sometimes the rock will move with the sand. Like a small sediment in a river.
Now the reason it leaves trails, is because A. It's a rock. B. Since it's the dried out part of the desert (I know what I said), some sand will get blown into the cracks. But it takes a long time to recover the rock's trail of rape, destruction, and evil.

How does the rock change direction so suddenly? I cant really think of any logical reason....

They didn't say. I would guess just a change in wind direction
