  1. I thought this was LIFI: "Create a box with puts out a light formation a bit like a TV screen, at frequencies we can't see, then use little mirrors and periscope to send that image on to a mirror in each room. For different connections simply have multiple pictures and set the device to only display picture one or picture two. This would be instant and the only flaw I see is that if something blocks line of sight. So simple use a tiny disco like globe and have multiple reflections to read from, the device checks multiple images for the most consistent pattern. Kind of like Spot the error. Fuzzy logic. Basically a camera would look at the light formation and there you have it. Basically you reflect the celling from the box room at a certain angle, and reflect the celling from the other room at a certain angle, put a picture with outgoing picture 1, and the computer has a camera which receives and sends light out. Just saying picture one. This way it's pretty much light speed." You should be able to get the idea from this.
