Immune hosts now dominate memory, while parasites and susceptible hosts decline in frequency. The parasites will soon be driven to extinction. Medium resolution (35956 bytes). Higher resolution (91814 bytes).

The Ancestral Program - consists of three ``genes'' (green solid objects).
The CPU (green sphere) is executing code in the first gene, which causes
the program to measure itself.
Medium resolution (11169 bytes).
Higher resolution (30463 bytes).
A Parasite (blue, two piece object) uses its CPU (blue sphere) to execute
the code in the third gene of a neighboring host organism (green) to
replicate itself, producing daughter parasite (two-piece wire frame object).
Medium resolution (18826 bytes).
Higher resolution (47741 bytes).
A Hyper-parasite (red, three piece object) steals the CPU from a parasite (blue sphere). Using the stolen CPU, and its own CPU (red sphere) it is able to produce two daughters (wire frame objects on left and right) simultaneously. Medium resolution (22537 bytes). Higher resolution (57578 bytes).
These are two images from the VRML Visualization of Network Tierra. This visualization represents the Tierra network environment though the ``eyes'' of the digital organisms themselves. Digital organisms are able to perceive conditions on the net by using the TPing sensory mechanism (sort of like echo location in bats). These images visualize the data provided by TPing.
Wide view of Network Tierra visualization. This is a view of a medium sized Tierra network, with about one hundred participating machines. The machines are located at ATR in Japan, The University of Delaware, The Santa Fe Institute, The Free University of Brusells, and the Swiss Federal Institute in Lausanne. Each machine is visualized as a set of spheres (one orange, one blue, and a few yellow-green), as described above. The network is represented from the perspective of one digital organism, located on a specific machine (in Santa Fe). The spheres representing the hundred machines are arranged onto the surface of a cone, with the point-of-view machine at the tip of the cone (a little below and left of center). The remaining machines are arranged in spirals on the surface of the cone, but with their distance from the tip proportional to the time that it takes the TPing message to cross the net and return. This network transit time is the most meaningful measure of distance on the network, and it is provided with the TPing data.
