They used to have it years ago in K2, a dynamic GUI that updated as the values updated. Arthur's brother wrote it.

It used an interesting idea that exapanded on the ideas of dependencies and triggers to also include GUI updated. There were some special attributes that described the layout of the variable, and you did `show$val to display it. As the value of val changed (and all other values it touched or included), the GUI would updated for you.

Think Excel merged with K and you get the idea.
