CIT sculpture

I was over at the CIT (Canberra Institute of Technology) campus in the suburb of Bruce yesterday, and came across this sculpture in the courtyard enclosed by A, B, C and J blocks. I haven't yet been able to find out who designed and made it, or even its name (if it has one), but I like how it's set amongst native trees and bushes, almost as if it's old machinery, adandoned to rust and be absorbed back into the earth.
