Plethora creates simultaneous, localized, personal broadcasting networks that allow audiences to form on-the-fly and build their own media streams. The display ranges from personal devices such as phones, to embedded screens in kitchens. It uses Bluetooth LE beacons to emulate local broadcast stations that signal the proximity. Plethora inverts the relationship between mobility and the multiplicity of screens with which we interact on a moment-to-moment basis. It also considers media as migrating away from larger, high definition screens to a universe of personal, anytime, anywhere representations.
