Looks like https://www.vestaboard.com is that enterprising company.

I've never used it, but it does look interesting.

I don't think vestaboard ever ended up shipping. I was somewhat interested in getting one, but now I'm really glad I didn't put down a deposit. Original estimates were Dec 2018 ship date, now they say Summer 2020.

They are coming summer 2020, for about $2200. (I think it's been delayed a few times). They look cool. But for my personal use, not $2200 cool.
