Set something round on the hill and it looks like it's rolling uphill, but in reality it's rolling down due to the grade/curvature. It's a bit of an optical illusion.

The thing that throws me off here is the waterfall. Trippy. The low quality of the video probably helps with the effect too. |

I think, given that the water clearly flows to a point much higher than where it starts, then *falls* down to the starting point, that there must be some kind of pumping mechanism, hidden from view. If you watch the water, when it gets to the third "leg" it appears to pause before suddenly moving along again. I could be wrong, but I think there has to be something more than illusion and gravity at work here - water doesn't flow uphill! |

My take: Either a video composite, which would also account for the appearance of weird shadows and explain the perpetual motion; or
A hidden water source, and clever camera positioning.
