Reflect table
There's always that guy (or girl) who dominates meetings, saying the same thing over and over again, or just repeats what others say. We all find it annoying, and we all wish there was some way to make that blabbermouth aware of his (or her) social transgressions. Enter the Reflect table. Reflect monitors conversations and visualizes -- literally -- who has the table using an array of color LEDs. Microphones listen to all the talk and show who is currently talking, who talks the most, and who's being left out. This could be great for business meetings to tone down the "thinking outside the box," but could also be a terrifying ordeal on a first date.
