Hofstadter-inspired writing, with a helping of Knuth served in the comments. Also good in Mark's blog: Ribbon Hero is the future ( http://diveintomark.org/archives/2010/03/03/microgames http://diveintomark.org/archives/2010/03/03/microgames ) about learning/achievement games. That post included a link to Space Invaders Enterprise Edition ( http://eis-blog.ucsc.edu/2010/02/space-invaders-enterprise-edition/ http://eis-blog.ucsc.edu/2010/02/space-invaders-enterprise-e... ). The title by itself is worthy, but the post is about rule engines. That interesting point was not much discussed here: http://news.ycombinator.com/item?id=1131502 http://news.ycombinator.com/item?id=1131502 .
