It took me some searching to go back to 2006 and find a program (then in beta) called VI Wonder. I think the creator was one John Calicos (forgive spelling if recollection isn’t 100%). It involved a fairly large island with trees, flowers, grass etc. On this island were also two female, full bodied “avatars” who roamed around the island “discovering” what was there. Every now and then the two would meet to discuss and share what each had learned.
John offered the beta to several members of the forum as I recall and it was quite impressive to play with and witness the results.
Sadly, it appears to have gone by the wayside. The old site was http://www.qflux.net (quantum flux).
Almost sounds like something that would have appealed to Wouter and others.
If I turn up anything else in this regard, I’ll post it here.
