Complete computing system in 20,000 lines of code

I just finished watching Ian Piumarta's talk on the Viewpoints Research Institute project to build a complete personal computer system in 20,000 lines of code. While one way to do this would be to use APL, Ian, Alan Kay, Dan Ingalls, and the others working on the project have opted to go for building metacircular/self-describing systems. Among fascinating programming language and compiler topics, Ian discusses Val Schorre's Meta-II compiler compiler from 1963, which had a self-describing grammar. Fascinating stuff, and in my opinion critically important, since the only proven way to reduce software complexity has been, to, well, reduce software complexity - less lines of source code written in a simpler way makes for better, more maintainable software, and this is exactly what the project aims to do.
