What is a driving motivation? • Not directly connected to a task • Can never be satisfied • Depends on experience – not given at outset Curiosity! Curiosity depends on finding something interesting What is the concept of interesting? Has to “arouse” you Key Centre of Design Computing and Cognition – University of Sydney

The “Digital Clockwork Muse” • Multiple curious design agents • all creating “genetic artworks” • Peer-to-peer transmission of artworks • transmission of “interesting” artworks • Economy of novelty • agents rewarded for “interesting” artworks Key Centre of Design Computing and Cognition – University of Sydney
Situated Creative “Designing” Design agents send “artworks” that they find interesting to other agents. If other design agents find the artwork interesting they send back a an expression of interest. To be considered creative, design agents have to innovate in ways that other design agents can appreciate. Design agents that develop the same interests in the space of possibilities form “cliques”.
