Nice!

Though, $2000 is a step price.

I had some fun with using an Inkplate e-ink display - bough a bare 5" for €74 (a 10" with batteries is there €219). Smaller, but also way more affordable.

It connects via WiFi, and make it display random, vide https://github.com/SolderedElectronics/Inkplate-Arduino-libr....
