I am looking for examples of a ui element that allows users to modify a number either by typing or "interacting" with the number (slide, drag, +/- etc.)
The specific use case is where a user will input her salary (4-5 figures) but then also explore what happens to a visualization if she "plays around" with that number.
I am aware of Tangle, but are there other "reactive" techniques/elements for this purpose around?
