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.
