  There was also a system where some TV screen pixels were used to send data, but I’m struggling to remember how you were supposed to get it into the computer.

  I suspect that you needed to build some light sensor with a serial cable, that you held to the screen, but I’m not sure.

  This was in the Netherlands, not sure if it was done elsewhere.

    I had heard of this but your comment sent me searching for more info. I think you might be referring to Visicode.

      That looks interesting, but it’s not ringing any bells.
