The exhibition accompanying the launch of the book was unique in not only having a virtual version available on the internet, but also in achieving the first ever online virtual interaction with the development of an evolving form in a remote exhibition. A model of the system, called the Interactivator, allowed both virtual and actual visitors to make selections or propose (via a bank of switches) genetic information to influence the evolution of the form. The development of specific instances of the form was also influenced by the physical environment of the exhibition space, as detected by data from sensors of temperature, humidity, noise, smoke level and so forth.
The Interactivator could also reproduce itself by allowing the program of the model to be downloaded to remote sites. As it replicated itself each replication took on a divergent evolutionary path, the results of which could also be fed back to the central model to contribute to the gene pool.
The internet experiment was made possible by the generosity of Ellipsis publishers who hosted the website. Parts of this site can still be visited at http://www.ellipsis.com/evolutionary
