The Eighth Day -- The Eighth Day is a transgenic artwork that investigates the new ecology of fluorescent creatures that is evolving worldwide. The Eighth Day was shown from October 25 to November 2, 2001 at the Institute for Studies in the Arts, Arizona State University, Tempe. While fluorescent creatures are being developed in isolation in laboratories, seen collectively they form the nucleus of a new and emerging synthetic bioluminescent system. The piece brings together living transgenic life forms and a biological robot (biobot) in an environment enclosed under a clear 4 foot diameter Plexiglas dome, thus making visible what it would be like if these creatures would in fact coexist in the world at large. The Eighth Day presents an expansion of biodiversity beyond wildtype life forms. As a self-contained artificial ecological system it resonates with the words in the title, which add one day to the period of creation of the world as narrated in the Judeo-Christian Scriptures. All of the transgenic creatures in The Eighth Day are created through the cloning of a gene that codes for the production of green fluorescent protein (GFP). As a result, all creatures express the gene through bioluminescence visible with the naked eye. The transgenic creatures in "The Eighth Day" are GFP plants, GFP amoebae, GFP fish, and GFPmice

A biobot is a robot with an active biological element within its body which is responsible for aspects of its behavior. The biobot created for "The Eighth Day" has a colony of GFP amoeba called Dyctiostelium discoideum as its "brain cells". These "brain cells" form a network within a bioreactor that constitutes the "brain structure" of the biobot. When amoebas divide the biobot exhibits dynamic behavior inside the enclosed environment. Changes in the amoebal colony (the "brain cells") of the biobot are monitored by it, and cause it to move throughout the exhibition. The biobot has six legs. When the amoeba move in the direction of a given leg, that leg contracts, causing the biobot to lean forward. Often one leg will contract while another will stretch back to its original position, creating a more complex sequence of movement. Ascending and descending motion becomes a visual sign of amoebal activity. The biobot also functions as the avatar of Web participants inside the environment. Independent of the ascent and descent of the biobot, Web participants are able to control its audiovisual system with a pan-tilt actuator. The autonomous ascent and descent motion provide Web participants with a new perspective of the environment.
