The thing I love about this is the vehicles in the air. That would keep me on permanent edge because although they are secure id constantly be worried about them falling. It just changes the space into a bedknobs and broomsticks idea of inanimate objects flying. I think it just plays with the imagination through emotion which is something really nice to try and capture.
Italian architect Massimo Iosa Ghini designed the Quattro Punti per una Torre sculpture located in the University of Milan. Interesting siting -contrast with older building adds an anachronistic element.
