Continuos rendering with GH and Maxwell

Hi guys,

I've just discovered this video tutorial where the presenter seams to use a script (componenet) in GH to generate a certain amount of file images that can then be rendered in Maxwell, here is the link to the tutorial.

I was wondering if some of you are aware of this script and where can I get it.

thank you all
