Definitely check out the third one -- it's a larger-than-life sculpture of Nelson Mandela made of chicken wire. I was all O_O because it looks like him! I mean, seriously, chicken wire! The man who made it, Masimba Jefta Mwazha, "dreams of being acknowledged as the chicken-mesh wire genius of the world." I'd vote for him, definitely.
This is great stuff -- check it out.
