A virtual world for artificial intelligence.
Even though its development seems to have been stagnated for quite a long time, aiplanet is still a delicious piece of software which will always be worth downloading. The initial screen shows an empty blue sphere (actually covered by some water and an atmosphere too), which can be transformed into a living ecosystem by raising land, planting trees and placing animals on it. Are your oceans empty? just add some fish. Too much fish already? let the shark do its work. You can make all sorts of experiments in and with your small planet, from draining the ocean to flooding the lands, from modifying the climate to smashing asteroids (unless you place a missile defense, that is). All of this results in an experience which is half documentary, half game, and all fun. Thanks Dave, and good luck with your music!.
