RolandPiquepaille reports on revealing the inner states of complex machines through fractals : https://web.archive.org/web/20060117063840/http://radio.weblogs.com/0105910/2004/06/23.html
This interface consists of a clustered algorithm which regroups the myriads of internal states of a machine into a small number, and a fractal generator. By looking at these changing fractal images, you start to 'feel' the machine's 'thoughts.' The first practical applications should appear within five years, while self-evolving or self-repairing robots will not come before a long time, according to the researchers.
