  1. When you did the demonstration where we could see only a single point of light and by moving we could see a different point of light, I thought of something. What if we built a device which could scan the point across the entire room, transmit the point to a remote location, and then reconstruct all the points into an image? It would be like vision at a distance. And then there's this Greek word tele, meaning at a distance. We could call this hypothetical technology "vision-tele" to sound cool.
