Het schijnt erg populair te zijn onder software developers: Terrarium. Maar als fysisch geograaf intrigeert mij dit ook wel: “..you can program either herbivores or carnivores.. ..Once a creature is in the Terrarium ecosystem and competing for resources, this website can be used to compare its vital statistics against those of other creatures. The objective of Terrarium is to develop a creature that out-survives the rest”.
