VPRI (vpri.org) was already mentioned here. The goal of Alan Kay, as I understand it, to reduce complexity of computer systems - by making them smaller. k shows you potential results with this approach - doing things differently, you can have small and functional systems, so they could be easier to understand while remaining feature-rich.
