Among the many derivations of Blosxom to PHP, Python, Java, Lisp, Ruby, etc, this JavaScript version from Japan tickles my fancy. As often happens, I wish I understood Japanese so I could give more information, but there is the blosxom.js file and an index.html file (view source code for the page) and that appears to be it (local download of the two files here).

What popular languages are missing? Should someone create a Flash version next? :)
