It's really interesting to see how art, architecture and engineering mix together. You can have a variety of more practical applications in house building[1]. Or you can see more artistic, non-practical uses but are heavily rooted in engineering and architecture [2][3][4]. It's gets even more interesting when you throw robotics into the mix humans could create things that are physically impossible today.
