I remember Schmidhuber showing off "artificial curiosity" stuff a while back (e.g. http://people.idsia.ch/~juergen/interest.html http://people.idsia.ch/~juergen/interest.html ). In particular, ideas like "compression progress" have been influential on my own research about how to measure what's "interesting", and I've implemented a rudimentary version of PowerPlay (and a slight alternative) at http://chriswarbo.net/projects/powerplay http://chriswarbo.net/projects/powerplay (He's since applied these ideas to art, humour, etc. which I think is a nice thought, but not worth taking particularly seriously)
