In the 1990s, I went to a lab in Tokyo for a presentation, and they had me using a freestanding whiteboard. When the board got full, I grabbed the eraser but a few in the audience started going "wait! wait". I thought they needed more time to copy the writing, but then a guy came up from the audience and pressed a button at the side of the board. The writing surface scrolled off to the side and a printout emerged from a machine in the corner. |
