Analog Concept II

For my analog device I will be emulating a twitter type interaction and response using touch-sensitive LED lit panels.  A single unit will be constructed from an array of LEDs which are enclosed in the front by fogged plexiglas. The corners of the plexiglas will be outfitted with pressure sensors and I should be able to estimate by triangulation the location and magnitude of a touch activation. There will be a total of four of these panels and when one is pressed, then the others light up in the same place that the first was pressed simulating the broadcast event of the tweet.  Subsequent presses on other panels will light up the boards in like fashion while turning down the lights on the activated panel. The resulting interactions between the panels will be a sort of visual record or database of the communications between the user, the activated panel, and the "friend" array of similar panels.
