Brave New World is a site specific participatory art-work, which invites participants to provide their views(image) and emotions to the real time analysis and visualization system through Twitter. The system will generate a collective image of emotions and images about the space in real time. The work is designed to make virtual communication tangible to explore the relationship between people’s perceptions and both coded physical and virtual spaces. The colour of the emotion is based by Plutchik’s wheel of emotions. see the participation: searh #wmhere on twitter.
