Mass Art

Living on Huntington I have the chance to see Mass art on my way to class and they have a few pieces on display outside one of their buildings. I think that these two peices have something to say about art and technology. I don't know who made them but I would like to find out so I could better understand what its about.
This is me in front of a large oak section with my hand on a metal pipe that is sticking out of it where a branch has been sawed off at its origin.The oak piece is about 10-15 feet long and looks like it was split by the forcing of the pipe into it.

This second piece I can only describe as a windmill saw because thats what it is. The white scoops would theoretically convert the wind power to turning a gear which would move the saw to cut the wood, which is hard to see below the scoops. Upon inspection it doesn't look like it would be strong enough to actually cut the wood but the saw blade is real and sharp enough.

I think they both speak a little about how technology (the pipe and the saw blade) can destroy nature or art the wood when the two oppose each other.
