Description

TechnoSphere was a real-time, 3D simulation of an environment that was populated by virtual creatures. Users across the globe had the capability to create their own creatures through a website. TechnoSphere III, one of many incarnations of the original design, used an artificial life program and fractal landscape

. Despite limited available creature designs, no two would ever behave in the same way, due to chance interactions with its environment and other creatures.

Physically, the virtual landscape of TechnoSphere consisted of 16 km² of terrain. It was capable of supporting approximately 4,000 creatures, though other sources suggest that as many as 20,000 creatures typically would coexist in the virtual environment at one time. After the relaunch, it was explicitly stated that the software limited the number of creatures at 200,000. Because each creature's behavior was unique, no single event could have been predicted, though some significant patterns developed. For example, even though there was no explicit flocking

 algorithm written into the program, creatures could be found organizing themselves into groups, most likely impelled by urges to mate and eat. The programs that supported the website were scalable, and could be modified to support a larger or smaller community of creatures.

, which were variants of the parents, sometimes incorporating aspects of both parents and other times favoring one parent creature's attributes over the others. General behavior patterns had emerged, but it was difficult to predict what was going to happen based solely on a creature's design. The one thing all TechnoSphere creatures did have in common was that they would all eventually die.

There was only one gender in TechnoSphere, so the creature that initiated mating was the parent that ended up carrying and caring for the offspring. Creature behavior was directed by a set of algorithms called Creature Comforts, designed by Julian Saunderson. It dictated, for example, that mating behavior (recombination

Popularity

One report described the project's popularity by citing that the online version had attracted over a 100,000 users who had created 3,286,148 and growing creatures. Over the years in which the website was operating, the growing popularity facilitated necessary updates to the server software and hardware, causing website downtime and often slow response times.

Museums and education

Many museums and educators found the digital ecology interesting and some teachers even used TechnoSphere as a teaching tool. The technological innovations and digital images produced by the project were of such interest that temporary installations were put in at several museums, including the National Museum of Photography, Film and Television (now the National Media Museum) (Bradford, UK
