Imagine if the whole of your iPhone or BlackBerry glowed different colours when you received a call or text message. Recently Eastman Chemical Company went along to a "design storm" session at Art Center College of Design to come up with ideas on how Eastman's Tritan copolyester, a clear plastic, could be used in consumer electronic devices. Josh Nakaya, Kory Victor, Marcus Koosmann and Grant Poznick came up with the idea of using Tritan to create a 'glowing phone'. By treating Tritan with an optical brightener it would glow when ultra-violet LEDs strike it. As you'll see in the video above, the glow can be limited to the edges of the phone or cover the entire surface. For more info visit the Eastman innovation lab site.
