NoFlo's black boxes can always be opened and modified, whether there is another graph or JavaScript inside.

The tools for interactive prototyping for designers will be built on the foundation that we're building now. So the draggable/spring example could be inside of a black box that exposes the important variables. Designers can use that box as-is, but there is very little friction to seeing and experimenting with how it works inside.
