Self the system still exists - this isn't just archeology. The website is at http://selflanguage.org and the Git sources at http://github.com/russellallen/self

The VM compiles on recent OS X and x86 Linux and it's pretty fun to play with. There is something about the underlying simplicity of the object model and the immediacy and concreteness of the system which makes programming in it for me unlike other programming languages, even after all this time.

I should do up a new release though - the downloadable binaries are a few years old now.
