I remember being given a tour of the Lawrence Lab, at the University up the hill from here, when I was a high school student in the mid-60's.
They were telling us how, by 1980, all the world's energy problems will be solved by Fusion energy, which they were pioneering. Now, half
a century and billions and billions and billions of dollars later, they're still talking about "someday". Your idea about screens is analogous.
It's not a new idea at all, and several repro systems of the past were based upon it. But you're all long ways from understanding just how
complicated all this can become in practice. But it's fun to think about, and who knows, maybe you will stumble onto a new tweak.
