Art and design have shaped the values, social structures, communications, and the culture of communities and civilisations. The direct involvement of artists and designers with their creative works has left a legacy enabling subsequent generations to understand more about their skills, their motivations, and their relationship to the wider world, and to see it from a variety of perspectives. This in turn causes the viewers of their works to reflect upon their meaning for today and the lasting value and implications of what has been created. Art installations are harnessing modern technology to process information and to display it. Such environments have also proved useful in engaging users and visitors with real-time images and interactive art.
