Last time i checked it, it contained links to old/dead projects, which seems still the case. Anyway AFAIK there is no such a similar thing to Brython for ruby, and by that I mean a ruby implementation specifically written in JS and optimized to deal with DOM and browser environment in general (if anybody knows about something like that or is working on it please inform me). It'd be such a great thing to have!

Most of the work in the recent weeks has been improving the ruby <=> js bridge so that calling js methods/functions from ruby is possible.
