Phillip Linden, one of the Second Life founders, has a nice blog entry on “aLife and sLife”. Emergent systems are already being seen in Second Life and they are a fascinating part of the code being written by users. To date most of these systems have been fairly one-dimensional (objects that wander around and act like vacuum cleaners, or objects with simple talk scripts), however the potential for objects that interact with other objects and with users is nearly unlimited. I hope some coders are inspired and we see some fun experiments!
