gibberwocky provides gibber-style live coding controlling Max/MSP/Jitter and Gen. Easily create looping sequences, transform patterns over time, and dynamically create Gen synthesizers and modulation graphs using a JavaScript client that runs in the browser.
Download the package and place into your Max Packages folder. (On Windows, My Documents/Max 7/Packages, on Mac, ~/Documents/Max 7/Packages), then restart Max.
Once installed, simply create the object [gibberwocky] and then open the associated help file to get started.
gibberwocky should also be available via the Max package manager in the near future (5/16/2017).

Note that this is a reference for all three gibberwocky systems (gibberwocky.live, gibberwocky.max, and gibberwocky.midi); they share many objects in common in addition to having their own unique affordances.
Outside of the Max help patcher, there are a bunch of included tutorials in the browser-interface to get you started using gibberwocky.
