I completed my Ph.D. in the Brown Computer Graphics Group in the Computer Science Department at Brown University in May, 2002.
In my dissertation, I describe a framework for creating and managing on-the-fly procedurally generated worlds.
Computer generated mazes and three sheet weaves and mazes that I created. 
See my family tree to see what branch of the Dollins line I'm descended from.
Links to various Linux software and information that I use and like to keep tabs on.
Just so there's no confusion, I think the Harry Potter books are just great for children to read. Though perhaps not quite as good the Disc World books by Terry Pratchett.
Better still, every household, with or without kids, should have a subscription to Science News.
