Everyone knows what an Etch-A-Sketch is? Good.

Some of the newer variants rely on magnetic principles to apply the "sketch".

So the questions are raised

  • Could a grid be underlaid behind the display allowing electromagnetic pulsus to set "pixels"?
  • How far can that be miniaturized?

...Nemo has always wanted a reflective display, rather than a transmitted one.
