Certainty of Ambiguity continues our practice associating visual representation of self with personal data and codes of identity. This free-standing, data tapestry measures 17 x 17 x 3 inches. Its scale conveys a sense of intimacy, a feeling accentuated by the way you interact with it, using your cell phone to program your PIN numbers with text messages. A RaspberryPi3 computer running custom, python software controls the tapestry and lighting hardware. Materials: 2 Woven fiber optic thread panels, RGB LEDs and custom hardware, Raspberry Pi3 computer, aluminum and steel frames, Plexiglass, linen yarn, 3D printed sintered nylon base.
