Engineer Martin Fitzpatrick of Two Bit Arcade has created the “Etch-A-Snap”, a unique camera powered by Raspberry Pi that very slowly outputs images as magnetic drawings on the attached Pocket Etch-a-Sketch. The camera takes the picture, the picture is reduced to its simplest representation and is automatically sketched onto the board with the help of stepper motors that drive the drawing wheels in the proper directions.
Etch-A-Snap is (probably) the worlds first Etch-A-Sketch Camera. Powered by a Raspberry Pi Zero (or Zero W) it snaps photos just like any other camera but outputs them by drawing to a Pocket Etch-A-Sketch screen. Quite slowly.

Fitzgerald demonstrated this process with a picture of Doraemon and a deer.
