A longstanding machine intelligence project, the Virtual Intelligence Matrix, has a new release, VI Wonder.
"VIWonder is the latest machine intelligence project from Quantum Flux. VIWonder works with language-based information, and it acquires this knowledge by searching the internet on its own. When running, two VI's carry on a conversation with each other, on subject of interest to them; or they will respond to your input, and talk about whatever you ask them to. VIWonder can be run as a stand alone program, or installed as a screen saver."
