Michael Johanssons' 'Self-Contained' sculpture is pretty fascinating, taking random items (like a car) and stacking them Tetris-styles into a box. I really like the look of this sculpture; it's not only massive, but also uses some rather intriguing items to create its contents.
A trailer, for instance, is flipped vertically to fit in between the shipping containers. Michael Johanssons' sculpture sits in front of a house -- I'm assuming his house -- for extra support. I think this would be a pretty hilarious sight to behold in person!
