I used to sit around staring at my CD cases for a long time. No, I wasn’t having a nervous breakdown. And I don’t do drugs, so forget bad acid trips. I used to think about how some day laptop computers would be about the size of two open CD cases put next to each other. In fact, if we could get rid of the need for a frame around a screen, they could even fold in half once you closed this screen.

But then I had the thought: what if we just put a computer in a small pen like device, and had the keyboard and screen coming out of two small projectors: one would project the keyboard on the desk in front of us, and the other would project the screen as a hologram in front of our face. Scientists are already making progress on holograms, but the idea of this computer I had is far away. Until I saw this:

To quote my Mom: “I should patented that idea when I had it!”
