\bigskip  Paper 4, Rob Saunder's \citeyear{saunders2012towards} ``Towards  Autonomous Creative Systems: A Computational Approach''is  particularly interesting, as it  was the only contributed paper to emphasise all four of our themes. themes according to the  metric above.  Saunders asks: ``What would it mean to produce an autonomous creative system? How might we approach this task? And, how would we know if we had succeeded?'' He argues for an approach ``that models personal motivations, social interactions and the evolution of domains.'' Paper 10, d'Inverno and Luck's \citeyear{d2012creativity} ``Creativity Through Autonomy and Interaction'', also contains a theoretical engagement with these themes, presents a formalism for multi-agent systems that could usefully be adapted to model serendipitous encounters. These authors are also particularly concerned with \emph{motivation}, a theme that relates to our notion of a prepared mind and to the topic of embedded evaluation, described above. evaluation.  We believe that our clarifications to the multifaceted concept of  serendipity will help encourage future computer-aided (and
