actually, in all seriousness, I want that, but for the opposite reason. I dream of every digital file having a physical representation that I can order with my hands, on a shelf. Not every file, of course, but the entrypoint to each fileset. So when I take a sheet of paper off the shelf and lay it on my desk, an RFID sensor (or overhead camera) identifies it and loads the relevant files on my monitor. Just think, never navigate directory structures with keyboard and mouse ever again. I’d gladly take a motorized librarian’s ladder over a keyboard and mouse.
