Here's a hint: try guessing what they're made of.
This coniferous installation is the work of Floyd Elzinga, who uses three-dimensional sculpture, relief work and environmental installations to highlight "broken landscapes, portraits of trees and the aggressive nature of seeds." Here, he's welded together steel spade heads to create a series of massive metal pine cones.
