The first project I choose is Julian Hoeber's Demon Hill. It is a house that uses compound angle to disorient people in the house. People will lose the sense of normal gravity in the house. I choose this project because it shows the basic element to be attractive and entertaining: to give people refreshing and unusual feelings. From my point of view, the best way to do this is to use tricks to make people feel "unrealistic", to break up viewers common sense on reality. I think movies, novels and other performance are attractive also because people can have unusual experiences in those performances that they cannot feel in normal life.
