This is remarkable. Lasers were invented in 1960 as a point of reference.

The painted rope on two spools was also remarkable because of its simplicity - and it holds up today on explaining what a "download" is. ;-)

And even cooler - if we wanted to, I would wager a high school student could implement something along these lines using lego today. There's optical sensors, and you could rig up something to hold a pen like this [1] to render the image.

Imagine the effort, creativity and commitment they’ve put with the rope on two spools, just to let the watcher better understand how they were transmitting the images.

Why even this simple thing seems unthinkable nowadays?
