Somebody, not I, wrote a [delayed action oscillator]( as an Azimuth code project in Java; it built for me but I was only testing and never used it before transferring it from a google code repo to github.

[Here]('s the relevant Azimuth wiki page with ENSO references and some other open ie. suggested Azimuth projects are [here]( DAO is marked as closed but only in the sense that some code was written: further code would be great.
