Scrubber?

Seems like a pretty natural fit for controlling animation…

It would be great if a scrubber had some controls like playback speed and choice of {loop, back-and-forth, stop at the end} as reader-accessible parts of the view, instead of only exposed in the code. These can be convenient to manipulate while actively interacting with a model. See Desmos for inspiration: https://www.desmos.com/calculator/fsycejw4dz
