Wondering
How would you create a virtual screen for a laptop? ie, something that would shimmer into existence, show your images, keep light from bleeding through from the back, and disappear when you turn the laptop off?
Well, I remember when a friend showed me how he builds touch-sensitive screens. I remember thinking Well, that's obvious...now. So I wonder if this is, too. The first thing that occurs to me is a two layer approach -- something to block light from the back, providing a 'canvas' for the actual screen. So how would you block light? Some kind of interference pattern, like noise-cancelling, is my guess. But I don't KNOW....

If I knew how to do that, I would not be blogging but traveling in myh yacht around the world.

When you figure it out...please remember that I knew you when...
Absolutely!
