Don't be doubt to the 'traditional art' with some pad like 'digital-tools', it just a LCD pad, which you can write on it with some stress then it can display where you stressed with color change physically. The only button on it can clean the pad. So technically it is traditional art.

So spared was I that I decided to draw something in that boring English class. With the potential memory, I drew this unrecognizable Rainbow Dash.
This pad names 小米米家液晶小黑板, the sense of drawing on it just like normal paper, without cut pencil or erase errors.
