The "crazy" label is merely a hint to the inherent resistance of most programmers towards "visual" tools, disregarding them for reasons not-withstanding in this case. yet here it seems like actually the "visual" way is the approach with more fine-control and detailed (and maybe sometimes more complex as you embrace the async nature further). It was by no mean an indicator of any of this being a "new" or "novel" idea.

p.s. while it originally used to be acyclic graphs, I had to relax that constraint due to people's request.
