Scribit is a vertical plotter that can draw any content sourced from the web – and update it in real time.
It is mounted on a wall using only 2 plugs and a wire in between. You send it an image from within the app and it will start drawing (with support for 4 colors at a time).
Shipping is expected June 2019, but like with all Kickstarter-funded projects that may vary 😉
