XBox controllers in Jupyter notebooks

[Rob Beezer]

At Sage Days 70 last month, we saw Jupyter notebooks with XBox controllers used
as input devices (think multi-slider interacts).

I finally got the hardware and software all together and working on a local
installation. Once the SageMathCloud version of the Jupyter notebook server
catches up with the bleeding edge, I'd expect this to be possible via SMC.
