I have a problem. I am working on a weblication where a workflow will be defined using a GUI. The problem is that the workflows will iterate and fork and we need a GUI that supports this. To top it of the weblication will be used by non-programmers who have no prior knowledge of what a fork or iteration is.
What I seek is inspiration. The only source of inspiration I have come up with so long is Lego Mindstorms, a product for 10-tear-old with no programming experience, which comes with a graphical programming language.
Does anyone know of any other UI where fork and iterations are made available for a user who may not know what a forks or iterations are?
