Hi, I just thought I'd post here to let fellow livecoders know that I'm working on an environment very similar to fluxus, that is focused exclusively on the mac platform & uses Ruby as it's language.
It's nowhere near as advanced as fluxus at this point, but as said in the subject, it might be of interest. You can find it at http://github.com/aptiva/tranquil and to get an idea of what it's output currently looks like you can check out http://fjolnir.asgeirsson.is/tranquil/ – Fjölnir
